pre-calculate text triangles for all letters/numbers and then construct strings from there

[cornhundred]

In order to speed up the calculation of text triangles, we could try to pre-calculate all letters and numbers and then construct labels etc. from the single letter position arrays. We would have to keep track of spacing between letters so this might be tedious.

Also, in terms of reducing the size of the JavaScript, we could try making a smaller text2vect that only produces text triangles.
