Bunch of new features and dependency updates

🎉 🎉 🎉

This one is a nice juicy release! I finally got around to looking at all of those PRs that have been sitting around for a while, sorry for the delay everyone.

Included in this release:

• Bunch of dependabot dependency updates
• (#81) chore: fixes to tests (thanks @jdcmarques)
• (#80) chore: update Node to v16 (thanks @ramprasadagarwal)
• (#75 and #78) feat: introduce new options to overwrite commiter name and email (thanks @ozaner and @promise)
• (#82) feat: introduce new option to pick sub-directory in target repo to copy files to (thanks @jdcmarques)
• (#83) chore: switch to using Node to copy files rather than bash (thanks @jdcmarques)

An extra special thanks in particular to @jdcmarques who not only opened 3 pull requests, but also fixed CI builds which helped speed up the review process considerably!

v2.4.1: Dep Updates & Handle spaces in folder names

The majority of the work for this release involved refactoring unit-tests for a better architecture (see 43688e2) but it also includes an update to all dependencies, and fixes for the following issues:

• #29 - DeprecationWarning: Buffer() is deprecated due to security and usability issues
• #32 - Folder names with spaces are not supported

v2.4.0: Skip Empty Commits, Custom Tags, and goodbye initial commit.

This release comes with a number of new features / improvements:

• #26: The "Initial" commit is no longer created on empty branches, and instead only the commit with the contents is added.
• #23 / #27: You can now give an argument to the action to also create and push a git tag.
• #28: Introduction of a new flag that allows you to skip adding empty commits, and keep only those that change the target branch's contents.

Introduce custom messages, and history squashing

Two new features:

• squash all history on the target branch with the SQUASH_HISTORY parameter
• create custom messages for commits using the MESSAGE parameter, with support for certain placeholders.

This release is also the first release to have extensive unit-testing and code-coverage results.
