Renaming forEachLimit to _forEachLimit, adding mapLimit tests
Adding built file
I have fixed the unit test for mapLimit in #205, as well as introduced parallelLimit. The unit test was doing a batch size of 2 over an array of [1, 3, 2]. The iterator function sleeps for n*25. So, task 1 would finish first, and then task 2 would be started. Task 3 and 2 would finish at nearly the same time - leading to intermittent test failures. This has been fixed in #205.
👏 👏 👏 hooray!
