Add support for SCM+ #1378
Description
I notice that support for SCM was added #977 . However, I was also wondering if support for SCM+ could be added. Based on information from the rtlamr project, I believe that decoding SCM+ should be fairly similar to SCM as SCM+ is "Similar to SCM, allows greater precision and longer meter ID's."
The rtlamr project's scm+ decoding is available here: https://github.com/bemasher/rtlamr/tree/master/scmplus
I apologize, as this entire field is very new to me. I am trying to provide outputs of the signals captured, but while I am able to see the scm+ signals in rtlamr, I am having difficulty at the moment capturing the scm+ signals in rtl_433.
