 * Debouncing occurs after every raw matrix scan.
 * Use num_rows rather than MATRIX_ROWS, so that split keyboards are supported correctly.
 * If the algorithm might be applicable to other keyboards, please consider adding it to ```quantum/debounce```

-### Old names
-The following old names for existing algorithms will continue to be supported, however it is recommended to use the new names instead.
