"unselecting" left-hand rows is a wasted i2c transaction.
On the left-hand side, the ergodox uses a GPIO expander. It
does *not* change "direction" (input/output) of pins, it just
sets pins high or low.
But all the pins are written at once. There's no way to
change just one pin's value; you send a full byte of all eight
row pins. (Not all of them are in use, but that doesn't matter.)
So every pin is either +V or ground. This is in contrast
with the right-hand side, which is using input mode to make pins
be neutral.
So there's no need to "deselect" the rows on the left side
at all. To select row 0, you set the GPIO register for the
rows to 0xFE. The previous code would then set it back to
0xFF, then set it to 0xFD on the next cycle. But we can just
omit the intervening step, and set it to 0xFD next cycle,
and get the same results.
And yes, I tested that the keyboard still works.
On my system, scan rate as reported by DEBUG_SCAN_RATE goes
from 445 or so to 579 or so, thus, from ~2.24ms to ~1.73ms.

Refactors rgblight_toggle to use rgblight_enable or rgblight_disable
Use 'rgblight_setrgb_at/rgblight_sethsv_at' to control an individual LED

Performs the same bit comparison that the layer_move
functions perform

The custom matrix code was missing calls to matrix_*_quantum, disabling quantum features.

This link was broken. And the latest, live version of that keymap link doesn't line up with the docs below, so the link will now point to the older version of the file in the git history

One link in the summary (Modding your keyboard) referred to a page that
was deleted; the rest have been updated to point to the new names.
