text: Title: Generate Async and Sync client together at the same time
  Body: ## Problem
  
  In my project, i mixed sync and async operations together, so i have to use sync and async in the same project but not in the same context.
  
  ## Suggested solution
  
  Shall we just generate sync and async clients together?
  
  ## Alternatives
  
  for now i write two generator, and generate clients to different position. 
  but the problem here
  1. i have to commit the code along with code, which a little bit annoying 
  2. partial types feature does work anymore. because it share the same context between prisma cli and generated python model.
