Document the use of multiple schemas in the same project.

I am trying to use multiple schemas in the same project. When generating from the first schema, prisma works just fine, but after generating the second I get an error:

Unhandled exception:

@TanaseHagi This is a bug implemented by the binary engine, and I will do my best to troubleshoot and fix it.
