Is it ok that email marshaling/unmarshaling regexp does not recognize empty value?

[jozseftiborcz]

I was testing api generated by this tool where the schema used the declaration something like this in a response struct:
EmailAddress *openapi_types.Email json:"email_address,omitempty"

However, when the response contains an empty email field , the regex matcher does not fit so unmarshalling stop with panic.

I am not sure if this is the intended behaviour in the above case.
Anyway, the solution would be simply put a length check before regex validation, here:

I've submitted a PR here to tackle this issue.
