Reduce memory usage of GpsStatus objects.
A simple GpsStatus object uses 9K of space, given that it initializes an array
of 255 GpsSatellite objects.
This change reduces the memory footprint in the average case, and keeps the
semantics of the API and its GpsSatellite sibling objects without any changes.
In a best case scenario it brings the memory usage per object to 1K.
It's likely in most cases that only 20-50 satellites will be in view. So the
usage should not exceeed half of the original memory usage.
It was considered to keep the internal array but a SparseArray provided bigger
memory savings in the test scenario of ~700B.
