Crash on previewing some files

[Canop]

I've an example of a svelte file: See trishume/syntect#421

The bug is in the syntect library that I use for syntax highlighting.

This library unfortunately contains some panic and crashes instead of returning an error.

The options here seem to be

1. find another crate for syntax highlighting: I know none (I'll only consider pure Rust ones)
2. wait for syntect 5 to be available, assuming this bug would be fixed (if it isn't, it would be at least easier to contribute)
3. fork syntect and remove the encountered cases of panic (then wait for syntect 5, I won't try to maintain a dedicated fork longer than strictly necessary)
4. try to unwind the panic...

If you encountered the crash when previewing a file, please tell me.

I went for the temporary fork road to ensure I have a version of broot not crashing when previewing files.

Fixed by commit d75f758

Syntect 5.0 panics too, in a different way...
