Rebrand and fix bugs

[mttbernardini]

Taking over this project since the original is not maintained since 2022.

As I'm not planning on bringing this back to upstream, but rather deviate onto my own project, I changed all the plugin IDs and original branding/credits. This is a breaking change, so versioning of this project will start from 2.0.0, as it's forked from upstream at version 1.1.0.

Fixes:

• Quality factor should have 0.01 increments, and the label should display 2 decimal places.
• All bands should be off by default, so filters can be activated as needed, ideally reducing computing demand.

Other Changes:

• Don't build AAX and VST2. I only care about VST3 and AU for now.
• Updated JUCE 6.1.2 -> 7.0.12
• Deleted original branding, replaced with my own minimal credits (plugin version and my website).

TODOs:

• Setup GitHub pipeline to automatically build on tags and attach built artifacts (delete the old workflow). Not planning on providing installers, just the vst3 files so they're easier to copy around (and possibly provide a single combined windows-macOS universal binary).
• Have a look at upstream issues and check if there's anything relevant to fix.
