Enabled resolvers mapping files to contains rules calling a forge method

[MFSY]

Fixes #316

[crisely09]

Could you add an example or a test? do we have already a case where the hjson has a forge function?

Could you add an example or a test?

This is to match how mappers are invoked in this merged PR https://github.com/BlueBrain/nexus-forge/pull/315/files#diff-c86c44807067dc2a80f4c2bcfa7aa9ec26c580888cc7fbba71032bb14736c73f.

A forge instance should be passed when calling mapper(forge).map()

do we have already a case where the hjson has a forge function?

There is not yet a configured resolver with a mapping file using a forge method. But this is a matter of time.
