Make 'fetch' command faster, like rsync

[techieshark]

Description and Context

Could the hs fetch command be made to run faster? Seems like it should operate more like rsync where it would only copy files that differ. It is taking over a minute and a half to pull down the files. Note, I need to use the --overwrite argument in order to fetch all the differences and that seems to make it take much longer.

I'm using CLI version 4.0.0.

The specific use case here is I have a CI system that checks for differences between a git branch and Hubspot. I would like to have a cached copy of the Hubspot files, then run the hs fetch command to update any files in the cache that differ, then I would run git diff to check for changes between the branch and the Hubspot files. Obviously, having this take 1.5 minutes is not awesome for the developer experience.

Steps to reproduce

Run hs fetch --overwrite / path-to-your-files/

Expected behavior

If the local & remote files are mostly identical, it should take very little time (a few seconds at most).

The time it takes would increase proportionally to the number of differences.
