Allow multiple process_record() calls per scan
This is particularly relevant for, e.g., the ergodox EZ and other keyboards with slow scan rates. Without changing the API or behavior of individual process_record() calls, we allow a configuration flag to make multiple calls in a single scan. This will probably have miniscule effects on non-steno users, and it's not enabled by default for any keyboards. Added note about it to ergodox README. Signed-off-by: seebs <seebs@seebs.net>
