text: Title: Access to absolute path of schema file through client
  Body: ## Problem
  
  I want to locate the schema file my client is basing itself upon through the client, enabling me to find the absolute path of the schema.prisma file through python without much hassle. This would make debugging easier.
  
  ## Suggested solution
  
  A function that returns the a path object pointing to the schema.prisma file the client is using.
  
  ## Alternatives
  
  I'm not too sure, the generator could as well store the schema path in an environment variable while generation is occuring.
  
  ## Additional context
  
  My actual problem isn't related to the client, but adding it would ease debugging. My libraries need to find a config file stored in the same directory as the schema, and prisma is my only dependency that generates a client based on a file, so my first thought was to see if prisma had such a function. (I can't use an absolute path because in production, it could be installed to either a global namespace or a virtual one, so i can't bank on knowing where my libraries will be)
  
  Thanks for the good work Robert, I'm loving this client, it's my go to database solution for any project that needs one
