Make the trait public, so consumers can use it.
Also, implement it for node::Node, so we can later use this to access
the name from all three if we don't care about the enum type.

Replace our data_encoding usage with the implementation taken from
https://github.com/nix-community/go-nix/tree/master/pkg/nixbase32
Also uncomment some of the unit tests, and add a regression test for a
NIXBASE32.encode with a 32 bytes sequence.
The previous implementation of NIXBASE32.encode is wrong in that case:

This implements the nix-specific base32 encoding and decoding, exposing
a subset of the API that the data-encoding crate provides.
Nix uses a custom alphabet, no padding, and encodes bytes in reverse
order. The latter one is the reason we can't just use the data-encoding
crate directly.
Three odd corner case tests ported over from go-nix failed. We opened
b/235 to further investigate.

Stat exposes metadata about a given blob,
such as more granular chunking, baos.
It implicitly allows checking for existence too, as asking this for a
non-existing Blob will return a Status::not_found grpc error.
The previous version returned a Status::not_found error on the Get
request too, but there was no chance to prevent the server from starting
to stream (except sending an immediate cancellation).
Being able to check whether something exists in a BlobStore helps to
prevent from uploading in first place.
The granular chunking bits are an optional optimization - if the
BlobStore implements no more granular chunking, the Stat response can
simply contain a single chunk.
Read returns a stream of BlobChunk, which is just a stream of bytes -
not necessarily using the chunking that's returned in the reply of a
Stat() call. It can be used to read blobs or chunks.
