`hasSlice`

The hasSlice function returns a reactive object reflecting whether a given Slice exists in an Index, and registers a listener so that any changes will update current.

  indexId: MaybeGetter<string>,
  sliceId: MaybeGetter<string>,
  indexesOrIndexesId?: MaybeGetter<undefined | IndexesOrIndexesId>,
): {current: boolean}
