Support more paths ()
- Closes  

This pr makes it possible to use `~`, `..` and environment variables in
the `juvix.yaml` and all flags / input of the cli.

In the CLI, the shell will be responsible for replacing environment
variables with their value, so the usual syntax can be used. For the
`dependencies` field, I have implemented a parser that has some
restrictions:
1. Environment variables are given with the makefile-like syntax
`$(VAR)`
2. The three characters `$` `(` `)` are reserved for the environment
variables syntax.
    They cannot be part of the path.
3. `~` is reserved for `$(HOME)`. I.e. the prepath `~~` will expand to
`$HOME$HOME`.
4. Nested environment variables are not allowed.

Thanks @paulcadman for the feedback. I think we are ready to merge this
nightmarish pr 👻

Pattern matching compilation ()
This implements a basic version of the algorithm from: Luc Maranget,
[Compiling pattern matching to good decision
trees](http://moscova.inria.fr/~maranget/papers/ml05e-maranget.pdf). No
heuristics are used - the first column is always chosen.

* Closes  
* Adds a global `--no-coverage` option which turns off coverage checking
in favour of generating runtime failures
* Changes the representation of Match patterns in JuvixCore to achieve a
more streamlined implementation
* Adds options to the Core pipeline

* Changes the `juvix compile` command to use the new pipeline.

* Adds a separate EtaExpandApps transformation to avoid quadratic
runtime in the Internal-to-Core translation due to repeated calls to
etaExpandApps.
* Changes Internal-to-Core to avoid generating matches on values which
don't have an inductive type.

Parse JuvixCore with absolute paths ()
Filepaths within a Loc must now be absolute or an error is thrown when
mkLoc is called. This Loc is used when displaying errors.

This commit uses imaginary absolute file paths in the Core repl and Asm
commands in the cases (parsing a single expression for example).

Before this fix, the `core {repl, read, eval}` and `asm` commands would
crash if it encountered an error when invoked with a relative path, or
in the case of a repl when parsing a single expression.

JuvixCore to JuvixAsm translation ()
An implementation of the translation from JuvixCore to JuvixAsm. After
merging this PR, the only remaining step to complete the basic
compilation pipeline () is the compilation of complex pattern
matching ().

* Fixes several bugs in lambda-lifting.
* Fixes several bugs in the RemoveTypeArgs transformation.
* Fixes several bugs in the TopEtaExpand transformation.
* Adds the ConvertBuiltinTypes transformation which converts the builtin
bool inductive type to Core primitive bool.
* Adds the `juvix dev core strip` command.
* Adds the `juvix dev core asm` command.
* Adds the `juvix dev core compile` command.
* Adds two groups of tests: 
- JuvixCore to JuvixAsm translation: translate JuvixCore tests to
JuvixAsm and run the results with the JuvixAsm interpreter,
- JuvixCore compilation: compile JuvixCore tests to native code and WASM
and execute the results.
* Closes
