Rob Newberry 3114ccf568 GNSS: Increase size of hdop 
The valid range of hdop (horizontal diffusion of precision) goes
from 0-100000, but because we are using a uint16_t, we truncate
anything above UINT16_MAX.

This fix changes the size of the hdop member to a uint32_t, which
allows us to capture valid (but admittedly very poor) readings.
