Title: Fix gh-2836 - buildindex var row,col_prefix fix

Building an index with COMPRESS(FIRST) and variable rows, caused excessive
amounts of memory to be used when reading the index. Because, the when the
nodes were unpacked, the max length * numRows was allocated and retained per
expanded node.

This commit encodes the row lengths in the compressed format
