Change Extra.forbid to Extra.ignore

[Goldziher]

Hi there,

The usage of Extra.forbid is difficult to work with in other libraries, because it requires sanitizing data before interacting with this library. Is it possible to change Extra.forbid to Extra.ignore? Especially for Schema but also other models.

The Extra.forbid bits are intentionally added there, so that the schema classes do not support Specification Extensions in general.

If extra fields are needed, one may try to extend the class for customizations.

Hi,

Extra.ignore will also disallow extra values, but it will not raise exceptions.

If you want this library to be easy to interact with, I would suggest switching. I already wrapped this library in a lot if code to handle this, but it just adds a lot of extra complexity.
