If the mimetype of the message is in the `allowed_mimetypes` parameter returns

Parameters
----------
message: email.message.Message
Message to decode.
allowed_mimetypes: iterable
Iterable object with the mimetypes will be used the select the message to
extract its text. Only `text/plain` and `text/html` allowed or a
`ValueError` exception will be raised.
Returns
-------
message_text: str
Returns the plain text of the message. This method will try return the text
encoded to `utf-8`. If it can't, returns it with its original encoding. If
it can't find the text returns `None`.
Raises
------
TypeError
If the parameter is not an instance of :class:`email.message.Message`.
ValueError
If the value in the parameter allowed_mimetypes is incorrect.
