[lefte]

• Add support for MySQL 8.4
• Updated minor version for 8.0
• Refactored to source from the main branch

Bare minimum self-checks

What do you think of a person who only does the bare minimum?

• I've updated this PR with the latest code from main
• I've done a cursory QA pass of my code locally
• I've ensured all automated status check and tests pass
• I've connected this PR to an issue

Pieces of flare

• I've written a unit or functional test for my code
• I've updated relevant documentation it my code changes it
• I've updated this repo's README if my code changes it
• I've updated this repo's CHANGELOG with my change unless its a trivial change (like updating a typo in the docs)

Finally

• I've requested a review with relevant people
