update SymPy

As of PyCall v1.90.0, getproperty is overloaded allowing for x.method(...) syntax instead of x[:method](). This extends this style to SymPy objects pushing up the PyCall version number.

Also uses SymPy's det function for matrices of symbolic values, as the generic det no longer works.
