Round-off error in MFLI DAQ

When using the MFLI as MLFIDAQ setting the sampling frequency does not work for all possible sampling frequencies.

If my memory serves me right: settings = {'fs': 107e3, 'bandwidth': 'auto'} works, however settings = {'fs': 200e3, 'bandwidth': 'auto'} does not. It breaks in daq/settings.py when comparing with the domain.

If nothing speaks against it, a fix would be to change line 253 from PRECISION: int = 10 to PRECISION: int = 9 (seems to work then)
