rustler_precompiled 0.7.2 on Hex

Added

The RUSTLER_PRECOMPILED_GLOBAL_CACHE_PATH environment variable was added to enable
an easy way to configure a directory to fetch the artifacts before reaching the internet.
This is useful to make more predictable where the cache files will be located, thus
enabling users to use that directory as a repository for the artifacts.
This env var will affect all packages using this library.
Add the RUSTLER_PRECOMPILED_FORCE_BUILD_ALL env var to force the build of all packages
using RustlerPrecompiled. Be aware that Rustler will be required if this is set
to 1 or true. There is a new application env that has precedence over the env var,
which is the :force_build_all.

Automatically run the "app.config" mix task in the "rustler_precompiled.download" mix task.
This will trigger the project compilation and configuration, but will not start the app.
It's necessary to check if the module passed to the task exists or not.
You can deactivate this behaviour by passing the flag --no-config to that mix task.
The mix task "rustler_precompiled.download" is used in the step of publishing a package.
Stop throwing an error in case the metadata cannot be written.
This is because metadata is only necessary in the process of publishing the package,
and users may be running with "write" permission restrictions.
We now print a warning instead.

Restrict the change of vendor to "unknown" only if the target is a Linux system.
