Improve the report printing by shortening repeats #18

Closed whot closed 4 months ago

This refactors the report printing so we can put limits on things, in particular: a device with 3 or more vendor reports in a row or 3 or more identical fields in a row will now shorten these.

My Wacom Intuos Pro hid-recorder goes from 6235 lines to 844 lines which is a lot more manageable with puny eyes. Example for repeated vendor usages:

# ------- Input Report -------
