Minor bugfix for parameter automation

Fixed a bug in handling of user presets.

Universal platform support: iOS, iPad OS, MacOS (intel + M)

Fixed compatibility issue with Logic Pro

Minor change in how AU Parameters report themselves to hosts to increase compatibility with some hosts

"Low cut" setting will now be displayed in Hz instead of percentage

Thanks for the great support and the kind feedback!
- Improved the interaction behavior of the bands panel
- Added "MONO" switch for the low band (makes the low frequencies monaural before compression)
- Minor internal optimizations
