/*
  Checks if the provided string matches to a correct Media type format (MIME type)

  This function only checks is the string format follows the
  etablished rules by the according RFC specifications.
  This function supports 'charset' in textual media types
  (https://tools.ietf.org/html/rfc6657).

  This function does not check against all the media types listed
  by the IANA (https://www.iana.org/assignments/media-types/media-types.xhtml)
  because of lightness purposes : it would require to include
  all these MIME types in this librairy, which would weigh it
  significantly. This kind of effort maybe is not worth for the use that
  this function has in this entire librairy.
