tooth pattern

I revised the upper and lower tooth pattern to better fit with what @wdduncan and I have discussed.

I also added a dentition tooth pattern. Dentition takes the outputs from the upper and lower tooth pattern and adds dentition.

The reasoning for separating the pattern is to make the patterns cleaner and because the order of naming teeth are dentition then position (upper/lower) then tooth (e.g., primary lower molar tooth), so separating out dentition from the upper/lower pattern makes sense and prevents teeth from being named as just dentition without identifying if they are upper or lower.
