Implement SemVer-based comparison on oscal-version in XSLT Profile Resolver

[wendellpiez]

User Story

Picking up #1313 and #1272, this Issue tracks complete implementation of oscal-version property (including value comparison) in the XSLT-based profile resolver. This requires supporting Semantic Versioning.

When complete, this functionality will be validated via unit tests.

Goals

• Complete and test implementation
• Merge working code into develop
• Provide top-level unit testing cf [EPIC] Update XSLT profile resolver to current specification #1076 and Profile Resolution Requirement Driven Unit Tests #1087 (over rebase) - either merged, or on track to be merged

Dependencies

TBD: clarify dependency between merging this code and merging unit tests now in working branches.

Seems there is a nice PR ready for review and to potentially close this out. Assigned @david-waltermire-nist and @wendellpiez to take a look during weekly status update.
