Returns a tightly packed unique index for the specific model represented
by this wire. The mask is split into 3 sections the combination of
corresponding bits from the two lowest nybbles gives the connection type
in that direction.
00 = none
01 = corner
10 = straight
11 = internal The
second byte contains the thickness*6+side
