Propose a simple migration from classic canvas to this module for pdf.js

[cmahnke]

It should be possible to use vanilla pdf.js with this library using. After this comment I would like to propose to provide a copy and paste ready solution...
Currently I'm strugeling in setting this up:

• For npm something like overrides should work
• For yarn there was resolutions - but that only worked with versions.

But (real, as in transitive) dependency management doesn't seem to be a strength of both...
