ttl: Remove error-prone sync() calls
...
These methods are problematic, as with DMA in the picture, the
timestamp member variables did not necessarily reflect the last
submitted event timestamp (see GitHub #1113 ).
sync() is only very rarely used in typical experimental code, so
the methods are removed without a transition period.
Core.wait_until() can be used to busy-wait for a specified RTIO
timestamp value on the core device CPU instead.

ttl: Remove broken TTLClockGen.sync
...
The code currently doesn't compile because of a typo in the timestamp
field name. However, tracking event timestamps in software is
problematic anyway (e.g. with DMA, see GitHub #1113 ), so just remove
`sync()` altogether.

ttl: remove timestamp function
...
The general idea is that functions that work with absolute timestamps exist only in machine units versions, to help prevent floating point losses of precision. Time differences should be computed in machine units and then converted, e.g. mu_to_seconds(t2-t1).
This function would have had problems after ~50 days of running the device.
