- 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

-trigger settings
-multiple tone replay

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

- 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.

Fix rounding issues of times for ADwin: Added a PseudoclockDevice for each TiCo, which fixes using the wrong resolution in 'Device.quantise_to_pseudoclock'; overwrite 'collect_change_times' for TiCo, becuase floating point errors triggered errors during checkes of time deltas.
