Resync to current main branch
Although I have made continual updates, I didn't update the versioned tags and releases. V1.22 marks the current main branch. I've added support for Tobii Pro eyetrackers / LabJack T4 / Arduino interfaces etc. and several new stimulus times since the last formal release... Opticka is mostly used in Linux, following the clear recommendations of the PTB developers, but should still work on other OSes.
