Support for binary ids and rails custom fields

[pnegri]

This fixes a problem when you try to use columns that aren't integer or string, also, when you use Rails 6+ Custom Field Types. When you call active model sanitizers, active model converts array of parameters by calling serializers for each model field/column, if you call "id" directly on these models, it will bypass the rails serializers and cast and will try to use the field.to_s as column value, resulting into a wrong value on the reference table.

Example 1:
class SampleModel
  # id as binary 4444, but displayed and A-B
end

Example 2:
class SampleModel
   attribute :id, :binary_uuid (displayed as: xxxx-yyyy-zzzz-wwwwwwww but saved as binary hex. Tries to save the xxxx-...)
end

Example 3:
class SampleModel
   attribute :id, :advanced_binary_uuid_with_short_uuid_support (displayed as: 6Y0xqMpcRdnpLwHVFjprkX but saved as binary hex. Tries to save 6Y0x instead of binary hex)
end

Hey, @pnegri ,

I didn't receive notification about your PR, I'm sorry.

Do you think is it possible create a simple test to represent this case?

Hi, @pnegri I didn't merge it yet because we need some kind of tests. As soon as I have time I'll study about this Rails feature that I never used so I can't understand the problem/solution for now.
