Is your Feature Request related to a Problem or Annoyance?

This is NOT a necessary feature for me.
If it requires too much effort, please disregard this.

I'm mostly surprised that it wasn't already included.

Describe the Feature you'd like

Add and argument to specify the maximum number of selections that can be made.

i.e. If the new argument is limitSelect, then

```meta-bind
INPUT[multiSelect(
option(One),
option(Two),
option(Three),
limitSelect(2)]
```

Should produce a multi select list that will limit the maximum selection to 2

Alternatives

Maybe allow it to specify both max and minimum selections, and have the selections light up in the 'destructive' style (red) if the number of selections are above or below the range

Additional Context

This mainly for use with spaced repetition plugin for reviewing MCQs.

Start by locating the existing multiSelect input implementation and how its options are parsed and rendered. Determine where a limitSelect argument could be handled, then verify that selecting beyond the maximum is prevented and that existing multi-select behavior remains unchanged.
