feat(snapshot): sort selectors ascending

[iankressin]

Motivation

This PR fixes Issue #178

Solution

• I first create a vector sorted_snapshots from the relevant slice of snapshots.
• Then, I sort sorted_snapshots in place using sort_by.
• Finally, I iterate over sorted_snapshots to build the rows.

I could have implement Ord trait for Snapshot , but it seemed an overkill to me, as this is the only place in the codebase so far that requires such ordering. Once new sorting cases appears, the trait approach must be more suitable.

Looks good to me! Once CI passes, i'll merge this into main. Thank you so much for your contribution!
