Blocks of 256x256 data (little-endian)

1. byte: block type

:0 - "flat" block, bytes 2+3 -> height (short)
:1 - "complex" block, bytes 2-129: array of 8x8 two-byte height (short) values, '''double''' of the flat block value
:2 - "multilayer" block, 256 (8x8) variable-length blocks of data:
::byte - amount of layers (1-125)
::array of two-byte height (short) values, one per layer, '''double''' of the flat block value

All values seem to be clamped to the nearest multiple of 8.

Default sea floor is at '''-3720''', but there are places on the map which go way below that.

Extreme values over all map: Min: '''-16352''' (=absolute zero), Max: '''15000''', total value range: 3919 * 8 = 31352

Sea level (average, guessed): 1574 above absolute zero, '''-3760'''
