1. v4: Remove next-tick dependency …

   For years, we had a unique external dependency (the only non-dev
   dependency) called "next-tick" allowing us to schedule callbacks in
   micro-tasks, either to provide asynchronous browser API shims or for
   some specific logic where we would prefer to bring some asynchronicity
   in without the need of bringing the event loop into this.
   
   We were not too happy having this dependency because the name "nextTick"
   didn't ring a bell to most RxPlayer developers who never really worked
   with node.JS before, whereas the "microtask" concept is generally more
   known and understood in JavaScript environments, or at least is easier
   to look for on the internet.
   
   Moreover, now that we consider that a Promise object has to be
   accessible globally in the current environment as a precondition to run
   the RxPlayer (so IE11 is now only supported as long as `Promise` is
   polyfilled by the application, which almost everyone still
   supporting that target in a complex media application does anyway) and
   that specification-following Promise implementations include a mean
   to schedule microtasks, we have a very easy way to provide a shim in
   cases where the `queueMicroTask` global function is not already
   supported.
   
   So this commit removes the next-tick dependency and replace it by either
   the natively-provided `queueMicroTask` function or a Promise-based
   ponyfill if not, naming the result `queueMicroTask`, which should be
   much more familiar to JS dev and is a simpler implementation than what
   `next-tick` provided, we moreover now control.
   
   Its removal also means that now the RxPlayer has no dependency from
   an application perspective, which may eliminates some groups of issues
   applications sometimes have when doing weird things with their
   webpack/vite configs :p
   
   We may still have an issue for Promise implementations which do not
   rely on microtasks (or even event loop events, we shouldn't have an
   issue with those), but I would expect that the very large majority of
   Promise polyfills in use today respect that key part of the spec.
