Description

I know that EuclidianRing isn't technically legal for types that can overflow, but EuclidianRing[Int] and EuclidianRing[Long] come up often enough when doing abstract math that I think it would be better if alleycats had instances for them, and if you are doing Int and Long it makes sense to include Short and Byte too.

Research direction

Start by locating the existing Alleycats EuclidianRing instances and their related tests in the repository. Confirm how instances are organized for numeric types, then add coverage showing the requested Int, Long, Short, and Byte instances are available and behave as expected.
