inswapper does not fail gracefully when targeted index in UI is higher than number of faces detected in the image.

Read Troubleshoot

[x] I confirm that I have read the Troubleshoot guide before making this issue.

Describe the problem
When you try to target a face index that is greater than the actual number of faces detected, This is very easy to replicate. If you are swapping an image with x numbers of faces, in " Target Image Index " set it to a number greater than x.

Proposal: This should instead skip and move on to the next task rather than throwing an error and halting.

Thanks for the report. Been meaning to get this one recorded as an issue and resolved. Should be an easy enough fix.

In general I think index out of bounds errors need addressed because sometimes inswapper is enabled, but there is not a face to swap so it fails.
