Merge branch 'main' of https://gitlab.tuwien.ac.at/quantuminfo/experiment-control/labscript-userlib/leolab_devices

- add some code demos how to run the card

-the problem was just that the print commands already make the transfer too slow. then a buffer underrun happens

try to implement fifo mode. still some bug, it does not laod new data into the fifo memory and a memory underrun happens quickly

OrcaQuest: Always start acquisition. TODO: Check implementation in manual mode or disable manual mode.

-trigger settings
-multiple tone replay

-fixed some bugs with the data transfer
-single frequency output in replay mode now works fine

DCAM: Fix taking more than 1 image per shot. TODO: Understand the difference between cat_start and cap_snapshot better.

- added first code and headers to test/run the card.

Timebase AOM Driver: Changed transition_to_buffered to improve timing, because of problems when comparing a dict to h5.attrs directly.
