*	Small rework of optimal vs maxsols	Sebastiano Tronto	2025-04-17	1	-6/+7
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	I wanted to make the "optimal" and "maxsolutions" options mutually exclusive, but in the end I decided there is value in keeping both (e.g. for specifying a limit to the number of solutions when asking for "all" optimal"). Now optimal cannot be negative anymore, for the same reason of maxsolutions. The interface user (shell, UI) will have to take care of handling this in a way that makes sense for the user. Usually this means setting the maximum number of solutions to UINT_MAX (or a similar very high number) when the user wants "all optimal".

*	Big cleanup for appendsolution()	Sebastiano Tronto	2025-03-24	1	-96/+51
\| \| \| \| \| \| \| \| \| \|	With this PR the appendsolution routine is extracted from the h48 solver and the new coordinate solver and made generic. This has many advantages: - less repetition (even if the two versions are different enough that for now it was not a big deal) - smaller h48/solve.h file, which is already a big beast - easier to test the appendsolution() routine separately
