Bug description

We're using the library in OSS mode (using pageShots) and noticed that the root-level threshold parameter (described in the docs) seems to be ignored in the comparison.
Only the snapshot-specific threshold seems to be getting into account:

{
  threshold: 0.1, // this is never used
  pageShots: [
    {
       threshold: undefined // this is used, if defined
       ...
    }
}

Looking at the code seems to confirm this hypothesis: https://github.com/lost-pixel/lost-pixel/blob/main/src/checkDifferences.ts#L70-L71

How to reproduce

1. Use lost-pixel v3.22.0
2. Setup config with pageShots and generateOnly: true
3. Don't set any threshold in the pageShots' snapshots
4. Set a global threshold in the root of the config
5. For the example use a page that would produce a pixelDifferencePercentage below the specified threshold but greater than 0
6. Run lost-pixel with the meta arg.
7. See in lost-pixel action logs--> {"pixelDifference":681,"pixelDifferencePercentage":0.0004926215277780001,"isWithinThreshold":false}

Expected behavior

isWithinThreshold should be true.
