Allow users to adjust the build level

[NiklasPhabian]

We seem to instantiate STARE at the default build level

pystare/pystare/PySTARE.h

Line 29 in 7848bd2

static STARE stare;

Which seems to default to 5 right now in STARE.

We should think about ways of having users adjust the build level. This might give us a pretty good speedup if we lookup large collections of SIDs when we e.g. create Sidecar files for large collections of granules with STAREMaster_py
