Features:

1. Issues and Verifies VCs using the 1.0 and 2.0 VC Data Models
2. Has integration tests for VCs using both models
3. Has validators for validUntil and validFrom
4. Updates the timestamp validator to use the XML standard from the spec
5. includes an expanded suite with timestamp tests

NOTE: new features in the VC 2.0 release should branch from this PR unless they build on another feature in a sister PR.

• [x] add or borrow logic for validFrom (PR approved for this)

• [ ] check against spec revision history
• [x] use release of VC 2.0 context
• [x] Do we check credentialSchemas?
  • no
• [x] Do we check evidence?

• [x] Do we need to support node 14?
  • [x] drop support for node 14 and 16 (separate PR for this)
• [x] Add MAJOR Changelog entry as vc2.0 is the new default context / data model.

@aljones15 IMO we should drop support for Node 14 and 16 and that can be addressed in a separate PR.

awesome thanks for letting me, node 14 tests are failing probably because of the branches.

@OR13 this branch was used for the test suite for VC 2.0, but as that spec is still in progress, we might not release this build of this library. This PR also still lacks a few VC 2.0 features such as validUntil and validFrom. So this PR is not currently prioritized to my knowledge for merge or release.

@davidlehn obviously leave the branch update-vc-2.0 so other builds still work with it for now.
