Project should be renamed hyperdrive-protocol

I am creating a [new awesome page for Dat Project](https://github.com/aschrijver/awesome-dat/blob/fresh/awesome/readme.md) and find much terminology confusion, making it hard to understand what modules do, without going into the code.

Isn't this module providing a protocol extension to the `hypercore-protocol`?

The name of this repository and package should be `hyperdrive-protocol`. This is much clearer and more consistent (e.g. in an architecture diagram :)
