Add "how to run dev version" in the readme

Description

Sorry for this, but I couldn't figure out how to run in development mode.
When I clone the repo, it throws whispering module not found, and when I install whispering it uses the files from the pip install, not the cloned repo.

My current fix is to manually edit the imports.

Could you please add some instructions on how to run it locally in dev mode?

Thanks in advance!
