py-sympy: updated to 1.11.1

1.11.1
Changes

utilities
The 1.11 release introduced a regression when using lambdify with the cse=True option (introduced in 1.9) resulting in a list being returned for a lambdified expression that was not a list. This bug is now fixed in the 1.11.1 release.

1.11.0
Better support for integrating several different types of expressions.
The series expansion has seen several improvements.
The assumption system is now fully deterministic, so it should work in multi-threaded environments.
A new and improved Mathematica parser.
