-Note to self: adapted from ergodox EZ matrix
-The "column" and "row" in here actually refers to the opposite on the keyboard
-see definition of KEYMAP in v1.h, the grid is transposed so that a "row" in here is actually a "column" on the physical keyboard

- * This constant define not debouncing time in msecs, but amount of matrix

- *
- * On Ergodox matrix scan rate is relatively low, because of slow I2C.
- * Now it's only 317 scans/second, or about 3.15 msec/scan.
- * According to Cherry specs, debouncing time is 5 msec.
