Primary changes are to include/assimp/metadata.h, adding in the aiMetadata GetAiType function,
adding the operator= to allow an aiMetadata type to be assigned, adding a check for the
AI_AIMETADATA type flag as it can't be trivially memcpy'd.
operator= is implemented with a by-value argument as then the copy is made by the copy
constructor and we can just swap everything out and let the destructor handle the mess.
Implemented parsing of the "extensions" flag on all glTF2 Nodes. Doesn't use the ReadValue
helper function on numbers as it did not seem to fill out the Nullable structure properly.
Previously parsing a node caused the skin that was attached to it
to be parsed, which caused the skins node joints to be parsed,
which could cause the skin to be re-parsed leading to infinite or
at the very least exponential recursion.
The fix is to just get a reference to a temporarily uninitialized
skin as they were being parsed after the scene graph just to be safe
anyway. This way we avoid the recursion problem and all the references
will be valid in the end.
