Serialiser_Engine: Fix remaining problems with serialisation

[adecler]

NOTE: Depends on

BHoM/BHoM#857
BHoM/Test_Toolkit#247

Issues addressed by this PR

Closes #1620
Closes #1755
Closes #1737

Yatta !! Finally got all types working (at least those on my computer).

This fixes the serialiser itself but will be accompanied by a few corrections on the non-compliant types themselves to get it all working (see PRs in the depends on section)

Test files

If you have types failing on your machine, please make sure they compliant first. A common issue for example is an incorrect constructor for IImmutable classes.

Changelog

• Move RegisterClassMap and add serialiser for regex
• Take care of the case where a bitmap is null
• Handle Enumerable as top objects and GenericTypeDefinition
• Don't send nulls to versioning

Additional comments

FYI, A dummy object cannot be created for MaterialComposition because it has a restriction inside its constructor that throws an exception if that constraint is not met.

Have one still failing my end:

first had had a look at the dummy object created, and it is not valid from a BHoM point of view, and wanted to check if that is causing it. But does not seem like it. Creating a valid one still fails to de-serialise for me.

@IsakNaslundBh , it works perfectly fine for me so we probably need to do a screen share on this one:

After chat with arnaud, ready to approve as this generally makes things better (the tapered profiles does no de-serialise correctly on my machine on master either).

I have raised the following issues to get this fixed:
BHoM/BHoM#860
#1760

Approving on the basis that the rest is working as expected
