Register setting issue

With code from #8, which has been merged, so opening new issue:

Adafruit CircuitPython 7.3.2 on 2022-07-20; Adafruit QT Py M0 with samd21e18
>>> import board, adafruit_si1145
>>> si1145 = adafruit_si1145.SI1145(board.I2C())
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "adafruit_si1145.py", line 84, in __init__
  File "adafruit_si1145.py", line 127, in uv_index_enabled
  File "adafruit_register/i2c_struct.py", line 43, in __set__
TypeError: 'int' object is not iterable
>>>

I think these need to be tuples?

           self._ucoeff_0 = 0x00 
        
           self._ucoeff_1 = 0x02 
        
           self._ucoeff_2 = 0x89 
        
           self._ucoeff_3 = 0x29

fixed with #10

	self._ucoeff_0 = 0x00
	self._ucoeff_1 = 0x02
	self._ucoeff_2 = 0x89
	self._ucoeff_3 = 0x29
