Specify with homeSpan.setSketchVersion(char *).
Read back with homeSpan.getSketchVersion().
Also, MDNS now broadcasts three new fields:
hspn = HomeSpan Version
sketch = Sketch Version
ota = "yes" if OTA enabled, else "no"
These are all optional to HAP but useful if trying to keep track of version updates when using OTA and Serial Monitor is not available.
OTA pasword now stored in NVS. Use 'O' command to change from default. Note password is stored as MD5 hash, and is therefore unrecoverable. Changes to password DO NOT take effect until next reboot. Password CAN be changed even if OTA has not been enabled for sketch. Blank passwords are not allowed.
Stored password can only be erased with 'E' command.
A 16-byte SALT with a leading zero would be sent as only a 15-byte number. The chance of this occuring is 1 in 256, which is small but still significant. Solution is to specify required size of MPI output in loadTLV. This forces mbedtls_mpi_write_binary() to pad with leading zeros.
Also eliminated unused code (TLV pack_old).
Setup ID can now be stored in NVS and set dynamically with the 'Q' command. However, homeSpan.setQRID(char *id) will override if present, but will not change the default stored in the NVS. This default wil be used once again if homeSpan.setQRID() is removed from the sektch.
If the NVS is empty, the default is set to "HSPN" as in version 1.1.4.
