Projectkk2glider/companion archive support (#4017)

* Files moved to thirdparty directory
* Miniz library added
* Unused simulators removed: er9x, th9x, ersky9x
* Example of opening archive file .eepe2 (File->Open)
* File reorganization, bunch of files moved to storage directory
* Added StorageSdcard class to handle storage for radios that use SD card to store radio settings and models
