[FTheoryTools] More improvements

[HereAround]

• Document FamilyOfSpaces,
• Add CI tests for FamilyOfSpaces,
• Add CI tests for HypersurfaceModels,
• Add some CI tests for LiteratureModels,
• Add missing information to Morrison-Park literature models,
• Correct information in E6, E7, E8 literature models ("Tate form on Steroids"), including update of index.json,
• Add CI tests which construct all Weierstrass and Tate models currently stored in our database,
• Add property is_partially_resolved for hypersurface models (including documentation, test and printing),
• Slight improvements to content of literature model documentation.
• Fix load error of global Tate models upon saving it to file. Also, restrict this functionality currently to toric bases/ambient spaces only.
• Test all Tate and Weierstrass literature models also over a concrete base. This allowed me to detect a minor bug, which I fixed.

(More to come...) I guess large enough to stop at this point and address more things in a separate PR.

Would be great if the commits could be squashed next time.
