Allow postponing resume

Add an optional $postpone parameter to the resume() function: if true, multiple resumes will postpone the resuming to the end of the callback queue instead of leaving its position unchanged (defaults to false).

Fixes

1.0.3

Just wait when starting

Fixup execution order

1.0.2

Fixup execution order

Actively wait for shutdown

This release improves UX by actively waiting for the currently running loop to exit when calling start().

Amp v3

This release brings amp v3 support: the entire API was refactored, check out the new docs for more info: https://github.com/danog/loop

The new architecture also avoids memory leaks that may have been present in certain conditions in old releases.

resumeDeferOnce

Added a resumeDeferOnce method in the resumable loops.
Multiple consecutive calls resumeDeferOnce to will yield only one resume at the next event loop tick.
