Add more verbose versions of clockTicks

[martijnbastiaan]

Can be used to supply simulators such as Verilator with accurate timing information, which it in turn can use to produce accurate VCDs.

@cuddlefishie The current test strategy is to make sure that:

1. The new functions draw the same conclusions w.r.t. clock ticks as clash-prelude's clockTicks.
2. The new functions agree with each other.
3. The new functions match manually calculated clock timestamps

This does fail to test that the timestamps the functions produce actually make sense. I did check by staring at the output really hard 👀, but if you want me to write a proper test I'll do so.

I've been shamed by @hiddemoll, I'll do it anyway.

Looking great, thank you! I just have one small documentation nitpick but other than that this seems very nice!
