Buffered parallel processing of async iterables / generators.

}Iterates and applies the callback to up to bufferSize items from input yielding values as they resolve.
bufferedAsyncMap(input, callback[, { bufferSize=6, ordered=false }]) => AsyncIterableIterator
input– either an async iterable, an ordinare iterable or an arraycallback(item)– should be either an async generator or an ordinary async function. Items from async generators are buffered in the main buffer and the buffer is refilled by the one that has least items in the current buffer (inputis considered equal to sub iterators in this regard when refilling the buffer)
bufferSize– optional – defaults to6, sets the max amount of simultanoeus items that processed at once in the buffer.ordered– optional – defaults tofalse, whentruethe result will be returned in order instead of unordered
Merges all given (async) iterables in parallel, returning the values as they resolve
mergeIterables(input[, { bufferSize=6 }]) => AsyncIterableIterator
input– an array of async iterables, ordinare iterables and/or arrays
bufferSize– optional – defaults to6, sets the max amount of simultanoeus items that processed at once in the buffer.
