This patch corrects 2 issues with the LED matrix of the KDBFans KBD67 Lite (v3)
* Incorrect mapping of the right-shift, down-arrow, and right-arrow. (i.e. `NO_LED` positions of the `g_led_config` key matrix in the .c file do not match the `LAYOUT_65_ansi_blocker` matrix in the .h file.
* Remapping of the *LED Index to Physical Position* using physical measurements from actual keyboard and accounting for the southpaw LED position to define the true centre of the keyboard (more relevant to circular animations).
