Add a count argument to seek.seek

[haberdashPI]

I miss vim-sneak. I know that leap is supposed to be an improvement on it, but I personally find it to be worse. I like the minimal number of keys I need to hit (e.g. sab to jump to the first instance of ab), and using ; to advance to the exact pair I want is often faster than reviewing the set of keys I need to hit when using leap.

I think implementing sneak would be pretty easy (much easier than leap): API wise it would involve allowing seek.seek to accept count number of characters (defaulting to 1).

Implementation wise I think it would involve something along the lines of:

export async function seek(
  _: Context,
  inputOr: InputOr<"input", string>,

  repetitions: number,
  direction = Direction.Forward,
  shift = Shift.Select,
  include: Argument<boolean> = false,
  count = 1
) {
  const input = inputOr(() => {
     let keys = ""
     while(count > 0)
        keys += await keypress(_)
        count--
     }
     return result
  })

Happy to take a stab at adding this feature.

Sounds good to me! Alternatively I wonder if the handling of "accept multiple keypresses" should be moved into keypress (to avoid disabling and re-enabling input mode), but if the direct approach with keypress in a loop has good UX it's good enough.
