Easy workaround in rescript-vscode for instant error reporting

1

As it bothered me that rescript-vscode requires a manual save to update error reporting, I found out a little workaround.

Just use autosave by adding this to your settings.json:

  "files.autoSave": "afterDelay",
  "files.autoSaveDelay": 200,

It seems that autosave does not include formatting, so you do not need to disable formatOnSave.

NOTE: I only tested it in smaller files. If it affects performance too much, you could tweak the delay a bit.
