Need tool generate a fully resolved schema from building block components

I'm assembling profiles from lots of pieces (see https://github.com/usgin/metadataBuildingBlocks), but the full schema displayed by bblocks-viewer shows all the $refs to building block components that are being assembled, making it difficult to figure out if the resolved schema that assembles all the pieces is doing what you want. A resolved schema is also useful for offline testing and validation instance documents using tools like Oxygen.

PR #8 addresses this issue with python codes to generate resolved schema. Also includes a couple tools to generate JSON schema in parallel to the yaml-encoded json schema and check that the JSON and Yaml are equivalent. I'm a lot more comfortable reviewing and testing the JSON serialized schema.

To make the resolves schema visible in the BBlock view requires update to the bblock viewer code (see https://github.com/ogcincubator/bblocks-viewer/issues/5), and an update to the post processing workflow (Github action) in the Building Block Repository.

Review PR #8 first, since it addresses resolved-schema generation and JSON/YAML equivalence checks. Then inspect the bblocks-viewer issue #5 and the Building Block Repository post-processing workflow; done means the resolved schema is visible in the BBlock view and produced by the workflow for offline validation.
