coding: implement TCH/F9.6, TCH/[FH]4.8, TCH/H2.4, TCH/F14.4
Implement all CSD specific channel modes, except TCH/F2.4. All of these modes are more or less similar to each other. The TCH/F2.4 is more similar to TCH/FS and slightly more complicated.
FACCH/F and FACCH/H will be implemented in a follow-up change.
