Removed oldest v1 style of firmware signature and presence checks. Added debug helpers for T1 signatures. Support for v2 and v3 signatures, but can only update FW to v3-style signed. Support for debugging T1 signatures. Scripts and README for debugging v2/v3 FW signing scheme. Firmware in GetFeatures counts only v3 signatures as signed. Add documentation and comments about signing schemes like a sane person
