Table 9-29 "Values of initValue for ctxIdx of sig_coeff_flag" has had 6 extra values added at the end.

Table 9-4 says that initType 0 uses values 0..41 and 126..127

However, judging from 9.3.4.2.5, the new context values are added by equation 9-23 at locations 27 (for luma), and 15+28=43 (for chroma). This is fine for Chroma (e.g. for I slices, the state for a ctxInc of 43 will be initialised by the new initValue at position 127), but not for Luma.

I believe there are 3 problems with the definition of the CABAC values:

1. Table 9-39 says that ctxInc for sig_coeff_flag only takes values 0..41.

2. The new CABAC values have been added in the opposite order to the ones in the code (the same ordering problem as reported for intra_bc_flag in https://hevc.hhi.fraunhofer.de/trac/hevc/ticket/1179)

3. Table 9-29 has had the new luma initValues inserted at the wrong location (because equation 9-38 has changed to add on 28 instead of 27, all the initValues from position 27 upwards should have been shifted)
