Subject: [PATCH] Enable clippy on CI

Add a clippy configuration file configuring the MSRV. Add a github
actions job to run clippy on CI.

Please note the job does _not_ use `--all-targets` because doing so
causes:
```
error[E0554]: `#![feature]` may not be used on the stable release channel
--> src/lib.rs:46:54
|
46 | #![cfg_attr(all(test, feature = "unstable"), feature(test))]
```
