New format

This encoding uses uppercase and lowercase letters only. k-uniformity is encoded by chr(ord('A') - 1 + k). The possible vertex types are encoded as follows:

A: 3.3.3.3.3.3
B: 3.3.3.3.6
C: 3.3.3.4.4
D: 3.3.4.3.4
E: 3.3.4.12
F: 3.3.6.6
G: 3.4.3.12
H: 3.4.4.6
I: 3.4.6.4
J: 3.6.3.6
K: 3.12.12
L: 4.4.4.4
M: 4.6.12
N: 4.8.8
O: 6.6.6

Corresponding lowercase letters are used if the orientation of the target vertex is opposite to the orientation of the focus vertex.
