Hello,

I am submitting a series of patches for mmsd that I have been working
on. The patches have been successfully tested on PostmarketOS, Debian
on Mobile (Mobian), PureOS, and Fedora.

The patches fall into two catagories:
1) core fixes to mmsd to get it to work with several carriers
(including T-Mobile USA, AT&T USA, Telus Canada, and a Swedish
Carrier). 
2) A new plugin to enable mmsd functionality on Modem Manager. 

The Patches have been tested on both the Pinephone and the Librem 5,
and have been confirmed tested accross all major US carriers (as well
as several minor US carriers), Canadian carriers, French carriers, and
Swedish carriers. They been been likely tested on more carriers, but
the author can only confirm the above ones (as he has gotten positive
feedback for them).
