Use linear algebra like eveyone else

[frostburn]

This library was written mainly as an excercise in geometric algebra. GA has known issues with speed and memory compared to established matrix methods.

GA is a nice theoretical tool with a steep learning curve, but once you get it, everything tends to Just Work ™️ . With matrices you have to deal with torsion and all kinds of weird things because of the extra entries that don't correspond to blades in the GA sense. So linear algebra can have a steeper implementation curve than GA, but the speedup is worth it from a user's perspective.

Assigned to inthar mainly for discussion. This is a huge overhaul of the package if implemented.

We decided on using Sintel's temperament finder API.
