Comunica Composite File Query Source Identify Actor

A Query Source Identify actor that handles composite file sources.

This actor enables querying over multiple file URLs as a single combined source, such as:

{ sources: [{ type: 'compositefile', value: [ 'https://example.org/file1.ttl', 'https://example.org/file2.ttl' ]}]; }

This module is part of the Comunica framework, and should only be used by developers that want to build their own query engine.
