Additional CI tests from hyperform, fmft and mzv-dm

[jodavies]

These commits add some more tests to the CI, from the hyperform and fmft packages. Particularly due to the valgrind tests, this slows the CI down substantially, mostly because a lot of the slow tests come in the same "group" (forcer, fmft, and the slowest of the hyperform tests).

Some of the hyperform tests are manually excluded when running without flint, since their results rely on the sign convention of gcd_ when flint is enabled.

Other missing files are:

.diagrams_cache/*.dat
diagrams.frm
diagrams/diagrams.h
polynomial.frm

which can be in a separate PR if you prefer.

Ah, oops, I will add them in to the last of these commits
