Subghz decoder (#1646)

Browse Source 
* Initial commit - wip

* Half part of the transition of baseband processor.

* More SGD

* WIP, Weather refactor, UI improv

* Rename

* Added 4msps, and fixes

* Fixes

* princeton working

* Renamed proc_weather, bc now multifunctional

* Proto: bett

* FPS_CAME = 4,
    FPS_PRASTEL = 5,
    FPS_AIRFORCE = 6,

* Came Atomo, fixes

* Separate weather and sgd, bc of baseband size limit

* Fix display

* Save space

* More protos

* Dooya proto added

* More protos

* add protos

* More protos

* Move weather to ext app

* nw

* Revert "Move weather to ext app"

This reverts commit 8a84aac2f5.

* revert

* Fix merge

* Better naming

* More protos

* More protos

* Add protos

* Fix warning

* Add NeroRadio

* more protos

* more protos

* More protos

* Shrink a bit

* fixes

* More protos

* Nicer code

* Fix naming

* Fix format

* Remove unused

* Fix some protos, that needs a LOOOONG part with the same lo/high

* Modify key calculation
