Add (basic) support for Optional Content in Annotations

[Snuffleupagus]

Given that Annotations can also have an OC-entry, we need to take that into account when generating their operatorLists.

Note that in order to simplify the patch the getOperatorList-methods, for the Annotation-classes, were converted to be async.

I don't know that much about OC stuff, so maybe my questions are meaningless.
In the JS api there is an OCG object which allows to show/hide the corresponding OC layer, do you think it's worth spending to implement it ?
Do you know if OCG are widely spread in Acroform to make them more "dynamic" ?
I noticed this pdf few days ago:
https://bugs.chromium.org/p/chromium/issues/attachment?aid=558169&signed_aid=fm0hxVYNIjr9UKjjmKmk3w==
which allows to change the content from thanks to OCG and JS.
Anyway it isn't directly related to this patch... so we can chat about that in a separate issue.

Perhaps not, unless it turns out to be at least a somewhat commonly requested feature.

Do you know if OCG are widely spread in Acroform to make them more "dynamic" ?

I can only recall having seeing such a document once before, but of course I cannot find it right now.

Overall it looks reasonable.
