chore: advance supermodel3 to 0455189

The fork rebased on trzy e048c09 (Src/Version.h:32 now 0.3a-e048c09-mm), one commit touching the drive board outputs only; upstream_commit held there with upstream_frozen. The 0455189 release archives carry the same Games.xml, Music.xml and crosshair bitmaps. Notes name the arm branch commit ROCKNIX builds.
