Quantum number related methods for symmetric UniTensor

[pcchen]

How to get information about possible quantum number blocks and their quantum number? Now I have to print a UniTensor to see these information. Also when I try following two methods to a symmetric UniTensor, I always get some error.

# H_sym.getTotalQnums()
# H_sym.get_blocks_qnums()

• If my syntax is wrong, what is the correct syntax?
• Or this is a bug?

I think this is a bug related to the pybind part, will try to fix soon.
