Fix numerical noise on one more system
Complete support for the theta subgroup:
Faber polynomials and basis, analytic type determination,
generators and dimensions for quasi weak parts,
coordinate vectors, q_basis, constructions from laurent expansions,
possibility of specifying the desired behavior at the cusp -1

Bugfix: When determining the generators or dimensions for all
quasi parts also negative weight spaces have to be considered!

Consistently use the zero order (instead of the pole order)
in functions
