Updates needed for js8call 2.2.0

[kd2hbv]

Although JS8Call 2.2.0 can be installed on zbitx's 32-bit raspberry pi zero 2W, it can't run as it relies on some additional hamlib commands that are not included in the original hamlib.c in the sbitx code. This pull request adds in the missing commands. After this, js8call can run natively.

Note: The following changes need to be made to files on the pi to speed up js8call's opening. However, these files are not part of this repo, so these changes, so these changes cannot be checked in here:
