Subject: gn3: genodb: Remove db, nrows and ncols fields from GenotypeMatrix.

db is unused. nrows and ncols are available in the array and transpose numpy
arrays.

* gn3/genodb.py (GenotypeMatrix)[db, nrows, ncols]: Delete fields.
* gn3/genodb.py (matrix): Do not initialize db, nrows and ncols fields.
