[Feature Contribution]: Implement Data Source Registration per ADR-0006

[bderusha]

What happened?

When ADR-0006 is implemented:

• Developers can declare only the data sources they need for their project in the .csproj file
• New data sources can be added to this project without requiring additional plumbing

Note
This feature is related to proposed ADR-0014 which expands on this to extend support to external packages.

If ADR-0014 is approved before ADR-0006 is implemented, it may be worth bundling them together.

Code of Conduct

• I agree to follow this project's Code of Conduct

Feature Commitment

• I commit to contributing this feature as a PR and working with the GSF to merge this feature into the Carbon Aware SDK.
