Error parsing media type 'application/json; charset: utf-8'

Hi,

Hope you're well.

Getting this error, it's mostly the fault of the API end point returning a non standard response: 'charset: utf-8' instead of 'charset=utf-8'

Any chance of throwing in a fix to treat charset: utf-8 as if it returned the standard responce?

Thanks,
Chris

Start by locating Jersey's media type parsing entry point and reproduce parsing of `application/json; charset: utf-8`. Confirm the parser currently rejects the colon form, then add coverage showing the requested behavior and run the relevant parser tests; done means this response is accepted as equivalent to `charset=utf-8`.
