hash sums always recalculated

[ppoilbarbe]

Hash sums (MD5, SHA1, SHA256...) are now always computed even if the file ".deb-control" exists with the sums already calculated.
I don't know when it begun to do this but in the past it was not redone if already present.
We have a channel with very big packages (>1GB) and very rarely modified but all sums are constantly calculated each time we add a new little package, which is very time consuming (>15min).
The version of freight used is the latest one from master branch: commit db53121, date 2021-10-08

@runejuhl could you look at this?

For information: sums always calculated are done from files in .refs directory.
If I run clear-cache, then it rebuilds the .deb-control files, calculating the sums, then if calculates them again from files in .refs.

@yegorich sorry, don't have time to look into this at the moment.

FYI my previous patch to avoid repeated hashing was to avoid a similar scenario, namely that freight would hash all existing packages whenever we added new packages, making freight take an increasingly long time to run.

Is there a possibility to correct it ?
I dug into the code, but it's a bit out of my skills in bash.
