Implements attribute set literals without nesting. Technically this
already supports dynamic key fragments (evaluating to strings), though
the only way to create these (interpolation) is not yet implemented.
However, creating simple attribute sets like `{ }`, or `{ a = 15; }`
or `{ a = 10 * 2; }` works.
Recursive attribute sets are not yet implemented as we do not have any
kind of scope access yet anyways.
This is implemented using a new instruction that creates an attribute
set with a given number of elements by popping key/value pairs off the
stack.

Deriving Ord/Eq is required for the ordered BTreeMaps. Once interning
is implemented this will require some extra magic for the sort order,
but that's fine.

These are a bit tricky to implement because Nix technically treats
them as identifiers, and only if the identifier is not explicitly
overridden within the scope does it yield the expected literal values.
Note that weirdness even occurs with scopedImport.

Implements simple arithmetic operations (+, -, *, /).
There is some scaffolding included to pop and coerce pairs of numbers,
as the Nix language will let arithmetic operators apply to arbitrary
pairs of number types (always resulting in floats if the types are
mixed).

We are going to have a 1:1 drop-in replacement for the old-style nix
tools, and this starts implementing the cli parser part.
The first step is to have a simple integration test suite that can
verify that we match the nix CLI.
clap is a super complicated parsing library, but looking through the
rest they are either too opinioated to be of use for us, or depend on
clap as implementation.
