feature: parameter to set the level of schema resolution

[long-eared-owl]

Some endpoints might return a very complex object, including loads of other complex objects.
The resolution of the reference tree takes a lot of time. It would be great to limit this so the RapiDoc script responds faster.
This is not about the "Schema Levels to expand"-Feature, but about willingly dropping schema information to gain loading time.
Maybe it could be named schema-resolution-level.

Anyway: great work, I really appreciate RapiDoc. <3

Hi, so if anyone would wish for the same feature: you can always "cut" the schema tree by removing certain objects inside the openapi file itself.
