The Polymaker, BETA, COEX, Overture, addnorth, Numakers, FusRock and
AliZ presets that BambuStudio does not ship now live under
OrcaFilamentLibrary/filament/<Brand>/BBL. The BBL bundle now holds
only the filament presets BambuStudio ships, plus a few Bambu and
generic ones.
New "<product> @BBL base" presets carry the values these presets used
to get from BBL's own bases, so their settings on Bambu Lab printers
are unchanged.
