[INSTRM-925] Duplicate key W_XHP2FR present in raw exposures

Following problems processing LAM data, it has been noticed that the key W_XHP2FR appears twice in raw exposure FITS files from LAM and at Subaru.

This is evident from the file xcu.py in the ics_actorkeys repository:

Float(name='HP1fraction',
                         FITS=('W_XHP2FR', 'XCU_SHIELD_HEATER_FRACTION'),
                         help='frac power to shield heater: 0 or 1'),
[...]                   
Float(name='HP2fraction',
                         FITS=('W_XHP2FR', 'XCU_SPREADER_HEATER_FRACTION'),
                         help='frac power to spreader: 0 or 1'),
                         help='status of the heaters.'),

In addition to fixing this, could a check for duplicate keys in the form of a unit test be also included please?
