Add --xloop-all feature

[tylerweitzman]

@breuleux This new feature allows you to call --xloop-all as a CLI flag which will wrap all functions in the global namespace with xloop so that if any function in the script throws an error it gives you the opportunity to fix the error and keep going.

Hey Tyler, sorry it took me a while to get to this. I tested it, this works well and seems useful to leverage the loop more easily. Just needs a ruff format, also a few # pragma: no cover to shut up the coverage check (this functionality is generally not covered right now since I'm not sure what the best way to test it would be). Thanks!

I'll make the fixed.

Been using this a bunch and works well except when my debugger is attached. Readme calls out that limitation-- any ideas how we could conceivably overcome that limitation? Perhaps there's some way for jurigged to regain reloading power following a breakpoint by detecting resume?
