* fix lint errors in eslint config :)
* index.d.s: add /* eslint-disable @typescript-eslint/triple-slash-reference */
* improve eslint calling script
* add async-worker version of the SRT JS API with await/Promise support
+ potentially out-of-order RPC-back/result-dequeuing is possible
with a type of call-ID generator and callback-map that we prototyped
(but not used atm since the worker is only doing sync/blocking internally
with the current SRT lib binding).
* add various examples for async API ("classic" callbacks / Promise / await)
* add .eslintignore (should go with commit where we just call "eslint .")
* index.js: add missing semi
* async.js: fix method name litteral in epollUWait
* async.js: allow for accept method to use a timeout opt (defaults to false),
and a custom timeout value option (default to default timeout),
which can potentially be set differently than the general default timeout.
+ make the timeout value a static class property so that it can be
user-defined module-load wide. defaults to constant in module top scope.
* async.js: fix for a rejected promise, make sure we don't resolve anymore
+ add a custom timeout value argument to _createAsyncWorkPromise
* async.js: rm an experiment
* fix a lint error in example
* add types for async api and fix some details on binding API types
* export async API to index
* async.js: add some missing docs for private methods
* include async types in index
