YAN-1351 Mock pointings from HDF
Using data from https://confluence.skatelescope.org/display/SE/Simulations+--+PI+19+Version+1 the mock device now simulates a pointings stream with a configurable timescale.
Pointings are in the DOUBLE[3] tango format where values at indexes are:
- 0: seconds from MJD epoch
- 1: az in degrees (from the pointingcentre_coords and pointingcentre_frame)
- 2: el in degrees (from the pointingcentre_coords and pointingcentre_frame)
Seconds from MJD epoch at ns accuracy requires the use of double precision and is accurate until 2150 (+/- 292 years) according to https://numpy.org/doc/stable/reference/arrays.datetime.html#datetime-units
