feat: fix bug and expose instantiated resource info

[Falx]

Purpose

This PR has two purposes:

• Exposing information about instantiated components/resources.
• Fixing a discovered bug

Exposing information on instantiated resources

This allows users of Componentjs to query the instantiated registry for types. In our use case this allows us to discover certain instantiated classes that implement a given interface.

New public methods:

• ComponentsManager#getInstantiatedResources(): Resource[]
• ConfigConstructorPool#getInstanceRegistry(): Record<string, Promise<any>>
• ConfigRegistry#getInstantiatedResource(term: RDF.Term): Resource

Fixed a bug

A bug was discovered where blankNodes and literal could overwrite eachother in the internal registry. This was fixed by replacing all indexing code of resource.value to termToString(resource.term) and vice verca with stringToTerm(resourceId).

A new dependency on rdfjs-string was added for that.
