Calculate a pyramid's checksum.

tsmChecksumPyramid_col computes and returns the checksum for a pyramid. The checksum is defined as the sum of all the bytes of all the tiles modulo TSM_CHECKSUM_MOD.

This variation requests one column of tiles at a time.

Trace levels:

1: Show pyramid id at start, and checksum/time at end. 2: Show "." after each column is done, and checksum/time after each level. 3: Show cumulative checksum after every column.

You can specify whether you want to check the lrbt or jpeg tiles by using tsmSetReadTileFormat().
