Andrew Hutchings b657938709 MCOL-1068 Improve compression_ratio() procedure ...

* Uncompressed columns caused a miscalculation for compression ratio
* We now show a ratio such as 2:1 rather than a percentage
* compressed_data_size instead of file_size is used to show the
compression of actual data, ignoring the pre-allocated segment
