Serialize to something else than string

[NiklasPhabian]

When we want to load a STAREDataFrame into a geopackage, we have to serialize the stare covers, for now, we can do:

sdf['sids_serialized'] = sdf.apply(lambda row : str(list(row['sids'])), axis = 1)

Then load this DF into SQLite, and then call encode_stareblob(). Would be much nicer if we could get the data in through another serialization.

@TonHai1111 might you a suggestion? There must be an easier way of dumping numpy arrays into sqlite3blobs so we can avoid the whole encode_*_blob() business.
