Tests for Precedence of Preconditions

[JakeChampion]

Howdy, this project is excellent, I'm really happy to see it exists ☺️

I've been working on implementing support for Conditional Requests in a project and wanted to ensure I've implemented the precedence of preconditions correctly and I couldn't find any tests in this project for that section of the RFC.

I've had a go at writing out all the combinations possible from the precedence rules and I came up with 146 possible tests, I've included them in the section below.

My first question is, does 146 sound like the correct total? I'd like to ensure I've got all the combinations

My second question is, would including those tests in this project be correct? If so, I can possibly work on converting my tests into the format this project uses ☺️

Hello!

For the purposes of this project, it's probably best to focus on (3) and (4) in Precedence of Preconditions; (1) and (2) are focused on origins servers, and while and origin server can implement a cache, it's not really the focus here. (5) is also relevant, but as the tests show, range support is not widspread in caches, and difficult to work with in tests.
