I removed all of the even tones in one commit, and made other changes in this one, so you should read that one to review.
I added some beginner-friendly explanations of the new segmentation to lessons 4 and 7.
Some remaining issues/questions that may be tackled later:
pyi (lesson 8) and nyaq (lesson 13) are invalid word forms now. I left them as-is.
I left Óe and Ẻ in lesson 5.
In lesson 12 I don't know if the use of hóq is still correct. For example it might pick up a binding like sa rỉaq instead of actually referring to the questions being asked.
