Implement N3-Patch format

https://solidproject.org/TR/protocol#writing-resources

@lecoqlibre is working on a library that will take as an input the original resource and the N3 Patch request, and return the patched resource. And throw errors if there is something wrong with the N3 Patch request.

However it would be better if we could convert the N3 Patch to a SPARQL query to run directly on the triple store (with DELETE/INSERT queries). Because there is always the risk with PUT operation of erasing some data that has been stored.

Also see:
https://github.com/CommunitySolidServer/CommunitySolidServer/blob/main/src/storage/patch/N3Patcher.ts

We should keep on supporting the Sparql-Patch format, but maybe put the code in a different library.

Start by reading the N3 Patch protocol section and the referenced CommunitySolidServer src/storage/patch/N3Patcher.ts. Then locate SemApps' existing Sparql-Patch support and determine how storage adapters execute updates. Done means defining the conversion and error behavior, preserving Sparql-Patch support, and adding tests for valid and invalid N3-Patch requests.
