Provide BoundedEnumerable[Byte] instance

[ashleymercer]

Following on from typelevel/cats-collections#315 it seems that there is no BoundedEnumerable[Byte] instance but I think it should be easy to provide (following the same pattern as Int, Long and so on).

I'm happy to try to put together a PR for this, although might need some guidance on binary compatibility if it's an issue, since the obvious fix would be to make:

implicit val catsKernelStdOrderForByte: Order[Byte] with Hash[Byte] with LowerBounded[Byte] with UpperBounded[Byte]

into

implicit val catsKernelStdOrderForByte: Order[Byte] with Hash[Byte] with BoundedEnumerable[Byte]

I think that will be binary compatible. Trying it and running mimaReportBinaryIssues is the way to be sure.

If it doesn't work, a strategy I've used before is to make the old value explicit and deprecated, and create the new implicit that you want. But I don't anticipate that being necessary here.

@rossabaker mimaReportBinaryIssues came back clean so we should be good to go - thanks :)
