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

does this hold on all platforms? maybe comparing to source_path is safer?

[olevski]

This is always the case see https://docs.rs/walkdir/latest/walkdir/struct.WalkDir.html#method.new

I added a comment with the link to the docs.

But also I added an && to check that the source paht is a dir too.

[olevski]

Now it is like this:

            if f_ind == 0 && source_path.is_dir() && path_std.is_dir() {
                // If the source path is a dir the first entry of the walk is the same dir that was
                // passed
                // See https://docs.rs/walkdir/latest/walkdir/struct.WalkDir.html#method.new
                continue;
            }
