Add protos to the Ludwig project: DatasetProfile messages and Whylogs messages.

[justinxzhao]

We copy the whylogs proto wholesale, as this seems preferable to adding the entire whylogs project as a submodule, and AFAIK there's not an elegant way to reference another project's proto.

I've also included adjustments to the pre-commit and other linting tooling so that protos are linted, and autogenerated protoc proto python code is ignored.

@justinxzhao Is the plan to also push the pb2 files to Ludwig?

That's correct. The raw source files generated via betterproto look a lot cleaner, but we can't use them because betterproto doesn't support proto any types yet, which is used by the whylogs proto.
