Add filesize column

[pjfsilva]

This is an amazing tool to easily get these metrics and compare them.

One thing I think would add value is to add a Filesize column to the list of files as this is often a parameter we want to check when comparing compression results.

Unfortunately, I believe the file size is not important for comparison at all and as a result, I do not have plans to implement this. Sotty.
