[Idea] Add idx to API

type FindResult<T> struct {
  idx int
  data T
}

Find<T>(data stream<T>) (res FindResult, miss any)

Alternative Idx component

Alternative could be having Idx or Index component for cases where you need index.

However, if you need both idx and data you'll have to chain it with some "Get" component.

Problem is we currently only have lists.Get (I think?) and to use it with Idx one have to pack stream into list which kinda defats the purpose of the stream
