counter: Update test results to reflect recent PD changes.
counter: use HD44780 dump to check counter's reset_edge option Resetting counters depending on the LCD controller's R/S signal yields numbers that correspond to byte sequences that either "control" hardware (register access) or carry "data" (display text). Provide a test case for the rising edge of RESET. Existing cases already covered the falling edge of RESET which is the default.
Add some counter test-cases.
