copy zarr-python dev environment

[d-v-b]

over in zarr-python, we have been pretty happy with our dev environment. I am wondering if we should bring those benefits over to numcodecs. Specifically, we would make the following changes:

• use hatch for packaging
• use the same linting / pre-commit configuration as zarr-python
• use a src/numcodecs layout instead of numcodecs

Does anyone object to this proposal? I think it will generally improve the dev experience.

I bet no one objects if you are willing to put in the effort! numcodecs needs some more complex build, though, right?

it will generally improve the dev experience

Curious, do you have something specific in mind?

I'm mostly thinking of the hatch features we use over in zarr-python, like the option to run tests parametrized over python versions, environment-specific commands (e.g., for building docs), etc
