97a5c61f28 Fix an injectivity issue with saving the game
Fix an injectivity issue with JSON-encoding the entity map that was
causing the game saving to not properly round-trip. As part of this,
there's a refactor to the internals of the entity map to use sets
instead of vectors, which should also get us a nice perf boost.

8a1235c3dc Use menus for combat and picking up items
Refactor a bunch of stuff around to allow for polymorphically surfacing
an EntityChar for all entities, and use this to write a generic
`entityMenu` function, which generates a menu from the chars of a list
of entities - and use that to fully implement (removing `undefined`)
menus for both attacking and picking things up when there are multiple
entities on the relevant tile.

f37d0f75c0 Implement saving+loading the game
Implement ToJSON and FromJSON for all of the various pieces of the game
state, and add a pair of functions saveGame/loadGame implementing a
prism to save the game as zlib-compressed JSON. To test this, there's
now Arbitrary, CoArbitrary, and Function instances for all the parts of
the game state - to get around circular imports with the concrete
entities this unfortunately is happening via orphan instances, plus an
hs-boot file to break a circular import that was just a little too hard
to remove by moving things around. Ugh.

4882350f5d Don't walk gormlaks into walls
Because of the way lines are drawn, a specific configuration of
positioning for gormlaks would have them decide they desperately wanted
to walk *inside* a wall, which they would then both fail to do but also
always collide with whenever they tried to go anywhere else.

8a4220df83 Implement speed and ticks
Gormlaks now move 1/8th the speed of the character, which means we can
run away from them - yay!

Unfortunately this also introduces a bug where they'll eventually get
stuck and not do anything, so I'll be tackling that next.

6ab7cdfdc9 Only allow adjacent gormlaks to attack
Previously the isUnit function was falsely returning `True` for
positions that were one tile off in *either* direction from the
character, when it should've been *both*. Oops.

de8052cef8 Allow eating edible items
Add menu support to the prompt system, and an "Eat" command that prompts
for an item to eat and eats the item the character specifies, restoring
an amount of hitpoints configurable via the item raw type.

5c6ba40019 Display multiple messages per turn
When tracking message history, save messages associated with the turn
they were displayed on, which allows us to have the notion of the
"current turn's" messages (provided via a MonoComonad instance).

05da490185 Gormlaks attack back
When gormlaks see the character, they step towards them and attack
dealing 1 damage when adjacent. Characters have hitpoints now, displayed
at the bottom of the game screen, and when the game is over they die.

dd16166665 Describe what you see when you walk over items
Every step the character takes, describe the entities at that position
excluding the character.

7770ed0548 Add the beginnings of a prompt system
Add the beginnings of a generic prompt system, with exclusive support
atm for string prompts, and test it out by asking the character for
their name at startup

58fce2ec19 Progressively reveal the map to the player
As the character walks around the map, progressively reveal the entities
on the map to them, using an algorithm based on well known
circle-rasterizing and line-rasterizing algorithms to calculate lines of
sight that are potentially obscured by walls.

9ebdc6fbb4 Convert generated levels to walls
Add support for converting generated levels to walls, and merge one into
the entity map at the beginning of the game.

There's nothing here that guarantees the character ends up *inside* the
level though (they almost always don't) so that'll have to be slotted
into the level generation process.

f03ad6bbd6 Add cellular-automata cave generator
Add a cellular-automata-based cave level generator, plus an
optparse-applicative-based CLI for invoking level generators in general.

4d270712ae Add raws, loaded statically from a folder
Add raw types with support for both creatures and items, loaded
statically from a "raws" folder just like in the Rust version.

18551cdf30 Add a previous message command
Add a "previous message" command, triggered via ctrl+p.

I attempted here to get the message area to still take up a row of space
post-hiding the message, but failed - should revisit that at some point

2fd3e4c9ad Implement messages
Implement messages almost the same as in the Rust version, only with
YAML instead of TOML this time, and a regular old mustache template
instead of something handrolled. Besides that, pretty much everything
here is the same.

4ef19aa35a Add entities, and allow walking around
Add support for entities via a port of the EntityMap type, and implement
command support starting at basic hjkl.
