id3scan should be a bin tool

[cjcodeproj]

The id3scan tool should become a command line tool.

So instead of running

$ python -m musicscan.tools.id3scan

A user can just run

$ id3scan

This will involve a change in the pyproject.toml file.

[project.scripts]
id3scan = "musicscan.tools.id3scan:main_cli"

A specific main_entry function will need to be created.

Closing Notes

• Refactored some of the id3scan code to a breakdown with more logical function boundaries
• Incremented the pyproject.toml version identifier so the development branch can be installed independently from the production releases.
• Updated documentation
• There's a typo in the CHANGELOG.md. It will be fixed at the next commit.
