Feature Request

Describe the Feature Request

Now INT64 and UINT64 parsed in strange way: parseLong could return Number or Long It would be better to have an option to change this behaviour and deprecate this in future

Also it is possible to rework decimal type so it will work with point differently.

Also dict is now unable to use as keys complex types, fix that

Also add more types: (for example, variant can accept only tuple or struct)

Also add enum, tagged
