The problem with readFile and writeFile from text
[Data.Text.IO](https://hackage.haskell.org/package/text-2.0.2/docs/Data-Text-IO.html)
is that they use the system locale to determine the text encoding
format.
Our assumption is that all Juvix source files are UTF-8 encoded.
I cannot reproduce the issue with using the old APIs on my machine, it
can be reproduced on Arch linux. I'm not sure how to write a specific
test for this.
* Closes https://github.com/anoma/juvix/issues/2472
- Closes#1993
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 👻

This PR adds some maintenance at different levels to the CI config, the
Make file, and formatting.
- Most of the actions used by the CI related to haskell, ormolu, hlint
and pre-commit have been updated because Github requires NodeJS 16. This
change removes all the old warnings related to nodeJs.
In the case of ormolu, the new version makes us format some files that
were not formatted before, similarly with hlint.
- The CI has been updated to use the latest version of the Smoke testing
framework, which introduced installation of the dependencies for Linux
(libicu66) and macOS (icu4c) in the CI. In the case of macOS, the CI
uses a binary for smoke. For Linux, we use stack to build smoke from the
source. The source here is in a fork of [the official Smoke
repo](https://github.com/SamirTalwar/smoke). Such includes some
features/changes that are not yet in the official repo.
- The Makefile runs the ormolu and hlint targets using as a path for the
binaries the environment variables ORMOLU and HLINT. Thus, export those
variables in your environment before running `make check,` `make format`
or `make hlint`. Otherwise, the Makefile will use the binaries provided
by `stack`.

* Remove ParserParams
ParserParams is only used to record the root of the project, which is
used to prefix source file paths. However source file paths are always
absolute so this is not required.
* Add GetAbsPath to Files effect
The Files effect is not responsible for resolving a relative module
path into an absolute path on disk. This will allow us to resolve
relative module paths to alternative paths, for example to point to the
standard library on disk.
* Files effect getAbsPath returns paths within the registered standard
library
This means that the standard library can exist on disk at a different
location to the Juvix project.
A command line flag --stdlib-path can be specified to point to a
standard library, otherwise the embedded standard library is written to
disk at $PROJ_DIR/.juvix-build/stdlib and this is used instead.
* Recreate stdlib dir only when juvix version changes
* Add UpdateStdlib to the Files effect
* Add comment for stdlibOrFile
* Remove spurious import
