multimedia/py-mat2: Metadata removal tool

Simple Python port.  Tested on amd64 FreeBSD 13.0-RELEASE with Poudriere.
Portlint likes the port, as does Portclippy.

Will submit the GTK3 fronted (https://gitlab.com/rmnvgr/metadata-cleaner)
in a separate PR.

***
Metadata consist of information that characterizes data. Metadata are
used to provide documentation for data products. In essence, metadata
answer who, what, when, where, why, and how about every facet of the
data that are being documented.

Metadata within a file can tell a lot about you. Cameras record data
about when a picture was taken and what camera was used. Office
documents like PDF or Office automatically adds author and company
information to documents and spreadsheets. Maybe you don't want to
disclose those information.

This is precisely the job of mat2: getting rid, as much as possible,
of metadata.

mat2 provides a command line tool, and graphical user interfaces via
a service menu for Dolphin, the default file manager of KDE, and an
extension for Nautilus, the default file manager of GNOME.

The following formats are supported: avi, bmp, css, epub/ncx, flac,
gif, jpeg, m4a/mp2/mp3/..., mp4, odc/odf/odg/odi/odp/ods/odt/...,
off/opus/oga/spx/..., pdf, png, ppm, pptx/xlsx/docx/..., zip, torrent,
svg/svgz/..., tar/tar.gz/tar.bz2/tar.xz/..., tiff, wav, wmv, ...
