Dali compressed *.LPK (ST low resolution)
*.MPK (ST medium resolution)
*.HPK (ST high resolution)

Files do not seem to have any resolution or bit plane info stored in them. The file
extension seems to be the only way to determine the contents.

16 words palette
? table 1 size in bytes stored as plain ASCII text + cr/lf
? table 2 size in bytes stored as plain ASCII text + cr/lf
? array of bytes 'table 1 size'
? array of longs 'table 2 size'

No description of the compression method exists at this time.
