SID Firmware v1.63

1.63

• BTTFN: Fix keep-alive logic and re-connection after a TCD-reboot.

1.62

• SA: Shift frequency bands slightly to better match mic frequency response and possibly batch-to-batch dispersion; better pace-keeping; clean up arduinoFFT.
• IO14 is now mirror of the TCD's TT-OUT (in its original function); goes HIGH on start of temporal displacement, LOW on re-entry. There is no lead time. Note: There is no terminal for IO14. It is, however, accessible through a solder pad next to the ESP32, pin no. 8 from bottom.
• BTTFN enhancements in sync with TCD capabilities
• Code refinements
