Update UV v3 to Manifesto v4 and Manifold v2

[stephenwf]

Goal of this PR

• Add general support for imported modules into the UV for easier integration pre-webpack
• Update Manifesto to version 4
• Update Manifold to version 2

This will allow UV v3 to continue to get updates with additional support for Presentation 3 fields and bug fixes without maintaining more than one major version of the 2 libraries. This work will lessen the impact of https://github.com/UniversalViewer/universalviewer/tree/webpack and provides an incremental change to v3.

I've split the update into 5 commits.

• The first is supporting changes which adds some work-arounds for requireJS and a pattern for allowing node_module imports to be loaded "correctly" by requirejs or as correctly as is possible. This will be supplanted by the switch to webpack.
• The second is a change to the typescript config to open up node-style imports e.g. import { MetadataComponent } from '@iiif/iiif-metadata-component'.
• The 3rd is a big update of all of the typescript files to transition from the namespace imports to module imports
• The 4th commit applies some changes to the dependencies in the extensions
• This commit is ONLY generated files

Changes in loading

• The external IIIF components are lazy loaded, like the other modules
• You can now import an node dependency - so long as you add the module to the config.js and also apply the pattern from app.ts. It is not ideal, but a pattern that can tide us over until webpack
• There are 3 more files in the lib. If anyone relies on the contents of this folder statically, they will need to update that list.

This sounds reasonable to me, though I have not yet taken the time to closely review or test (it's VuFind Summit this week, so my calendar is packed). @edsilv, if you need my backup on this, please let me know and I'll schedule some time (and/or ask @Geoffsc to take a look).
