Singularity Registry HPC v0.0.25

This update includes bug fixes, organization refactor, and addition of several new features!

• Podman support is now added. The user can set podman to the default with shpc config set container_tech:podman
• This means that container_tech is now a settings.yml variable
• Automatically generated alias names for a container are now customizable, defaulting to {{ tool }} and allowing for also registry, namespace, and version.
• We now allow for custom test interpreter "test_shell" to distinguish from podman_shell and singularity_shell
• The command config edit allows for interactive edit
• Adding show --filter to filter list of modules shown
• We have split the documentation into user and developer guides to make it easier to find what you are looking for
• Added automated spell checking with crate-ci/typos
• Support for container features. E.g., if a container.yaml has features->gpu, the container technology knows how to process that to add appropriate flags.
• shpc get -e to show path to an envrironment file
• Added support for env section to render to bound environment file
• Allowing for a container:tag convention to be used for commands.
• List defaults to showing modules/tags one per line, unless --short used
