Parse a Content-Type header. It will not throw an Error if the header is invalid.

This will return an object with the following
properties (examples are shown for the string 'application/json; charset=utf-8'):

In case the header is invalid, it will return an object
with an empty string '' as type and an empty Object for parameters.
