Runs fennel using a Lua compiled with the same options as the host system, and with packages set up so it can find all the local Lua packages To shorten the dev feedback loop further, allows FENNEL_PATH to be set on the command line so you can point directly it at the Fennel sources for some library you're working against instead of having to run nix-build and compile them to Lua
