feat: add dataset publishing

[olevski]

This adds commands under rnk dataset deposit for managing uploading data to zenodo or listing active deposits in zenodo.

For now we have only zenodo, but we can expand to other providers in the future.

Handling credentials is a bit rudimentary - via an environment variable. But it is sufficient for now and we can expand it later on. If you generate an API key from zenodo then you can use that.

Here are the added commands:

Usage: rnk dataset deposit [OPTIONS] <COMMAND>

Commands:
  cp    Copies the data from a location into a data deposit
  ls    List all depositions for the specific provider
  lsf   List all files in a specific deposit
