Initialize a new MMS2R::Media comprised of a mail.

 Specify options to initialize with:
 :logger => some_logger for logging
 :process => :lazy, for non-greedy processing upon initialization

 #process will have to be called explicitly if the lazy process option
 is chosen.

 Get the phone number associated with this MMS if it exists.  The value
 returned is simplistic, it is just the user name of the from address
 before the @ symbol.  Validation of the number is left to you.  Most
 carriers are using the real phone number as the username.
