First, checks whether a context is stored locally before letting the super class do a fetch.
This can be used when converting JSON-LD with Comunica-related libraries, such as rdf-parse.
The loader has an internal cache that stores fetched documents for 30 minutes by default.
This is to prevent spamming a context URL in case there are many requests.
This cache can be disabled by setting the ttl to 0.

rdf-parse.To use this, add this document loader to the options of the call using the
KeysRdfParseJsonLd.documentLoader.namekey. All extra keys get passed in the Comunica ActionContext and this is the key that is used to define the document loader.
