Add support for groups of blocks up to 999. New nodes are defined for
groups of 100 blocks, similar to 10s but with colours encoded in param2
using 3 separate palettes (4 groups per palette, since each group of 100
is checkered with light and dark).
Also add multipart number nodes support, including improved finding of
number nodes and determination of which set of blocks each belongs to
(using 2 upper bits of param2 to encode the direction the number is
extended from the central block).

Floating number blocks are added based on 8x16 textures of the digits
0-9. These are placed above the closest top level block to the average
position of the top level blocks, and automatically updated when the
numberblock is changed.
