Fixed bug:

- Audio Channel Mixer now can reverse mirrored Left & Right channel

Fixed breaking bug:

"supportsaudioprocessing" : true

was stripped from the config file - so no audio data was being processed (hence a broken wallpaper)

- updated version file to v2021.09.10.2

Bugfix:

- Block mode would only draw lines to half the height of the screen.

Added "Normalize Audio'' as part of a setting of the Equalizer

Find it here:

Visualizer Extra -> Equalizer -> Normalize Audio

This will make the Audio bars always have the same length, not depending on the source volume.

Note that on very low source volume, this might give some weird unexpected results - because it will boost it to the target level regardless.

Updated version in project.json

Features:

- Added Hold Line option
- Added Block mode

This was quite a big change, with fundamental changes, so I expect some configurations to be broken - please let me known and I will have a look

Fixed issue with Array with zero elements being stretched - which wasn't possible
