This PR adds a third IOI, LIOI_X0Y9, for special handling on the 100T. Without this change,
LIOI_X0Y9 has empty "bits" in tilegrid.json. Note there is no RIOI at Y9,
since the bottom right region of the 100T is high speed serial IO.

I wasn't really thinking; I just assumed each device would have two such IOIs that needed special handling. But the 100T has three it seems: LIOI_X0Y9, LIOI3_X0Y109, RIOI3_X57Y109

LGTM, let's wait for CI

On a side note, this could be a hint that also the 200T requires a similar adjustment
