Show both size and actual size of files #742

Closed fkorotkov closed 6 months ago

fkorotkov commented 6 months ago

Right now we show only actual size of files on disk which excludes empty blocks of the recently introduced sparced format in #671. This makes impossible to get info about disk size that we just set via tart set.

Here is an example of tart list output before the change:

Additionally, tart get will print actual size with a 3 decimal point precision which will help to track growth in disk images for our templates.
