Upgrade to Pynac-0.7.12

[rwst]

In Pynac-0.7.12:

• symbol replacements should inherit flags; care for exp() (Doctest: Make Expression normalization work with symbolic powers #23861)
• check series and polynomials for exponent overflow (series yields wrong result #12589)
• fixes and improvements to Singular conversion (Doctest: Bug in symbolic GCD computations involving complex I #23793, Doctest improvements to symbolic GCD #23845)
• make factor() as capable as Maxima's (Replace Maxima with Pynac/Singular in Expression.factor() #23835)
• immediate exp(x)^y simplifications
• immediate log() of small powers simplifications (Doctest fix for: wrong symbolic comparison of log #23224)
• make degree functions return numeric
