Update the project name.

Why am I doing this?

Mainly 2 reasons:

1. I want to add a GUI in the future and shell out to the CLI to perform most of, if not all of the actions. I realized that if you had protobuf installed, it will cause problems.
2. I want people to be able to find it easily. Just searching buf will 9 times out of ten get you to protobuf, bufusb is a little different and is also very easy to distinguish as an image flashing software
