Implement OnePseudoInverseOfSemigroupElement for more types of elements #1062

It's not currently implemented for:

• elements of Rees matrix semigroups;
• elements of regular Rees 0-matrix semigroups over non-groups;
• elements of free bands;
• PBRs;
• Matrices over semirings (other than finite fields);
• there are probably more.

Also harmonise OnePseudoInverseOfSemigroupElement and OneInverseOfSemigroupElement by having a 1 argument version and a 2 argument version for them both (currently OnePseudoInverseOfSemigroupElement takes 1 argument, and OneInverseOfSemigroupElement always takes 2 arguments).
