Call For Additional Maintainers

[AldaronLau]

I think it would be generally good to have at least one additional maintainer on this crate to not only increase the bus factor, but lessen the amount of work I need to do to maintain this crate. Originally, whoami was added to https://github.com/rust-bus in case I got ran over by a bus, but now that's gone.

I think ideally additional maintainers would have one of the following qualifications:

• have collaborated on any software project with me
• depend on multiple features of whoami in another project they develop
• depend on whoami in a larger project

There are a few different pieces I could use help with:

• Q/A testing around releases
• Issue response / PR review
• 2.0 development / preparation

I can also continue doing any of them, if other maintainers are uninterested.
