Create `rget pin` subcommand

There needs to be a way for a user to save the digest of the files received and ensure that if fetched again that the contents match the last digest. There are a few uses for that:
- Telling a friend to download something: send the file over email
- Downloading dependencies for a software build: check the file into git
Rough UX of what I am thinking:
Append to the file if this URL is missing, otherwise verify
rget --pin-file rget.sum https://github.com/etcd-io/etcd/releases/download/v3.3.13/etcd-v3.3.13-darwin-amd64.zip
Append/create URL entry to a pin file for a given URL:
rget pin https://github.com/etcd-io/etcd/releases/download/v3.3.13/etcd-v3.3.13-darwin-amd64.zip

I guess it would be also useful to pass the hash of the single file being downloaded directly as a parameter.
If the receiver trust the instructions, a single copy paste would suffice:
rget --hash b41491157076ccfa52e7b9b0ee695afd24c5d720ea9e40933ef908e69ec19368 \
https://github.com/etcd-io/etcd/releases/download/v3.3.13/etcd-v3.3.13-darwin-amd64.zip
I did something similar in https://github.com/mkmik/runck, but also conflating the issue of executing an installer (as a proof of concept for an alternative to curl | bash)
