Add support for dummy handbells

[jaa46]

Requested by Tom - shouldn't be too hard. Need to find a way to pass keystrokes to Muster. Perhaps the Handbell Manager could be persuaded to do this...

This appears to be happening already: Mike Pidd, and also Richard Johnston, are modifying Handbell Manager.

Should update the documentation to mention these:

Richard Johnstone has written various programs: http://ringingtraining.pbworks.com/w/page/139677120/ringing_software_controller_interface_programs?mode=embedded

Tom Farthing has also written a Python utility for serial port dummy handbells, which is attached. He wrote to the change-ringers mailing list last Monday with some details.

I wrote a small program that enables me to use my serial port dummy handbells with muster. I've had my program working on both a windows computer and a mac.

It is a python program. I had to pip install pyserial and pynput. In the bell_config.json file
on a windows computer, I give an entry like
"serial_port": "COM3",
and on a mac, I give an entry like
"serial_port": "/dev/cu.usbserial",

On the mac,
I had to make a change to "allow an app to control your computer". Here is what I did:
Finder -> Applications -> System Preferences Security & Privacy Privacy Tab Allow an app to control your computer. I allow terminal and then use a terminal to run the program

The program sends a keystroke every time a button is pushed or released on my dummy handbells. That's equivalent to ring on signal 1 of 1 in Abel. In the bell_config.json, I can set the signal_map to control which signals are used and which keystrokes will be sent. I usually use j and f.

and Adrian and Mike extended Handbell Manager:

A version of Handbell Manager, 1.4.0, that now works with both RingingRoom and Muster, and still works with Abel and Beltower, is now available. Windows only I’m afraid. The required simulator must be selected from the run menu as for the version 1.2.3 If Handbell Manager. It avoids keystrokes being sent to inappropriate processes, though for RingingRoom the RR window must have focus.
It is hoped that the source code will be available through the current Handbell Manager repository soon.
