feature request: manual reload

At the moment the only way to reload a file seems to be to re-open it again.

I'm working in WSL2 and editing my files there with VS code, but CQ-editor runs in Windows. Therefore the automatic change detection doesn't work.

As I guess the above is hard to fix, I'd wish for a simple reload command (e.g. triggered by CTRL-R) that just reloads the current file.

PS: Thank you for this great tool!
