[regression] Update results.csv

9f327c02 changed the compression method
for LDM, so the results are slightly different.

I've re-tested LDM on some larger inputs and everything seems fine.
These ratio changes just seem to be noise. There is generally a 0.01%
swing in ratio, sometimes better sometimes worse, but never large.
