Even the standard QMK matrix_scan() function can give about 2 times higher scan rate (if compiled with optimizations enabled) if the COL2ROW matrix layout is used instead of ROW2COL. Although the ID80 PCB is wired using the ROW2COL matrix layout, it is possible to transpose the matrix from the QMK standpoint, so that "columns" would correspond to horizontal connections, and "rows" would correspond to (mostly) vertical connections; in this case the matrix could be handled as if it had the COL2ROW layout. The matrix layout change makes the older VIA JSON layout definition incompatible, but the corresponding JSON was not yet accepted to the VIA repository, so it should still be safe to make this change.

The QMK PR qmk/qmk_firmware#8930 changes the matrix layout used by the IDOBAO ID80 keyboard (the matrix is transposed, so that the faster COL2ROW scan routines may be used). Update the VIA layout definition according to these changes.

Description
Transpose the matrix layout of the ID80 keyboard by swapping
MATRIX_ROW_PINSwithMATRIX_COL_PINS, flippingDIODE_DIRECTIONfromROW2COLtoCOL2ROW, and adjusting theLAYOUTmacro accordingly.Even the standard QMK
matrix_scan()function can give about 2 times higher scan rate (if compiled with optimizations enabled) if theCOL2ROWmatrix layout is used instead ofROW2COL. Although the ID80 PCB is wired using theROW2COLmatrix layout, it is possible to transpose the matrix from the QMK standpoint, so that "columns" would correspond to horizontal connections, and "rows" would correspond to (mostly) vertical connections; in this case the matrix could be handled as if it had theCOL2ROWlayout.The matrix layout change makes the older VIA JSON layout definition incompatible, but the corresponding JSON was not yet accepted to the VIA repository, so it should still be safe to make this change.
