67415bfabe Add an abstract base-class, which all the various Stream implementations inherit from 
By having an abstract base-class, it becomes a lot clearer exactly which methods/getters are expected to exist on all Stream instances.
Furthermore, since a number of the methods are *identical* for all Stream implementations, this reduces unnecessary code duplication in the `Stream`, `DecodeStream`, and `ChunkedStream` classes.

For e.g. `gulp mozcentral`, the *built* `pdf.worker.js` files decreases from `1 619 329` to `1 616 115` bytes with this patch-series.

Given that we're using modules, meaning that only explicitly `export`ed things are visible to the outside, it's no longer necessary to wrap all of the code in a closure.

Support InkAnnotations without appearance streams (issue 13298) (#13301) 
For now, we keep things purposely simple by using straight lines (rather than curves); please see https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/PDF32000_2008.pdf#G11.2096579

e6601f4582 Convert the code in src/display/canvas.js to use standard classes 
This gets rid of *a lot* of boilerplate that stems from our old way of simulating classes, and it actually reduces the filesize noticeably.
For e.g. `gulp mozcentral`, the *built* `pdf.js` files decreases from `318 404` to `314 722` bytes (~1 percent) with this patch.

4078dd856c Clear some Arrays, rather than re-initialize them, in src/display/-code 
It's generally better to re-use the same Array, by clearing out all of its elements, rather than creating a new Array.

da22146b95 Replace a bunch of Array.prototype.forEach() cases with for...of loops instead 
Using `for...of` is a modern and generally much nicer pattern, since it gets rid of unnecessary callback-functions. (In a couple of spots, a "regular" `for` loop had to be used.)
