Add the missing transforms to bring parity with patsy / R. about formulaic HOT 5 OPEN

Is the above list up to date? I'm curious if I could be of any help.

Hi @lorentzenchr !

Obviously I didn't get to this in the timeline intimated. COVID has led to some changes in various trajectories, including with me heading back to Australia (a big transition given I have four kids). My plan is still to get to this, but you can feel free to explore implementing cr, cc and te if you are interested. I am far more opinionated about the implementation of C.

Note that it was my intention to write these from scratch after learning the mathematics behind them, as I did the others. This allowed me to write things with high performance in mind, and avoid copyright issues.

Hope you and your family are fine.
In my opinion, C is the most important of all. I'll have a look at the spline basis, let's see.

I'd be interested in your opinions about C.

Hi @lorentzenchr ; sorry... lost the thread here a bit. I've implemented support for different contrast matrices now in #70. Feel free to take a look :).
