Generate SHACL shapes from the linkml YAML model

SHACL is the standard accepted by the W3C, it now starts to be integrated in multiple projects to perform data validation (e.g. Ontotext GraphDB triplestore, RDF4J).

Unfortunately ShEx shapes cannot be converted to SHACL shapes, and there are no work to integrate ShEx validation directly in existing products, so the use of ShEx to validate data is limited at running uncomplete third-party softwares

Describe the solution you'd like
The same way as ShEx shapes are generated it would be ideal if SHACL shapes could be generated from the linkml YAML model
