[Feature request] Show progress during compaction

[MacroPower]

Recently I changed one of my backups to use 1GB blocks, instead of 200MB.

My issue is that there are an incredible number of files, and during compaction, I have no idea how much work is left to do.

In fact, it appears to simply hang here eternally. Ref: #3084 This is not the case - duplicati is chugging along, albeit slowly.

Would it be possible to get a progress indicator for this step? If not XX%, at least some indication that the operation is running outside the profiling log. When the progress bar simply freezes for days without updating any text, it does look like the backup has hung up completely.
