Investigate macroTasking

Feat: Make asynciterator asynciterable

2

In particular this logic https://github.com/LDflex/LDflex-Comunica/blob/f01ece6fa8cee720061efd5ddd23ed82921555e4/src/ComunicaEngine.ts#L158-L215 should be implemented as the `[Symbol.asyncIterator]` method of `AsyncIterator`

UnionIterator skips not readable subiterators

During some performance tests, I saw that the UnionIterator called `read()` on all its sub-iterators, even if only...

perf: uses setImmediate() implementation from tiny-set-immediate

Giving the option of setting the autoStart for the "from*" functions

4

Hi everyone, I wonder if it would fit the library's design to give functions like [`fromArray`](https://github.com/RubenVerborgh/AsyncIterator/blob/0f8909b1c736e6a7aed4d1213a5d9260b8ea22af/asynciterator.ts#L2248) the option to set the autoStart to a user-defined value. If this is the...

## Cloning a ClonedIterator doesn't preserve HistoryReader from original source ### Description When cloning an `AsyncIterator` that is itself already a clone, the new clone doesn't share the same [`HistoryReader`](https://github.com/RubenVerborgh/AsyncIterator/blob/0933ec72ea252b7026c3f659dc3832e94d4bd377/asynciterator.ts#L2012)...
