Upgrade to pynac-0.7.2

[rwst]

Pynac-0.7.2:

• add libfactory interface; unconditionally replace GiNaC GCD with Singular (Giac GCD if available); this fixes Infinite loop in gcd() via pynac-0.2.1 #10284; it means that Singular is now another Pynac dependency
• reenable unconditional use of Giac if available (Enable Pynac's Giac support #21885)
• fix zeta expansion around 1 (behackl) (Document Stieltjes constants #21899)
• fix Giac GCD doctest fail
• fix NaN unpickling (uncovered in Fix crash and remove pexpect-Maxima usage in Y(m,n) #20939)
• fix Flint underlinking (fbissey)
• fix dilog problems (Doctest fix for: dilog(RR) should return an element of RR #19906)
• fix Singular GCD interface
• fix is_real(positive^real) (Doctest for: Positive raised by a positive power is not known to be real #21940)
• better error message with evalf of some orthogonal polys
• improve pkg-config usage
• add internal rising/falling factorial
