Further changes to coefficient contexts.
This patch alters the balance of context between the coefficient bands (reflecting the position of coefficients within a transform blocks) and the energy of the previous token (or tokens) within a block. In this case the number of coefficient bands is reduced but more previous token energy bands are supported. Some initial rebalancing of the default tables has been by running multiple derf clips at multiple data rates using the ENTOPY_STATS macro. Further balancing needs to be done using larger image formatsd especially in regard to the bigger transform sizes which are not as well represented in encodings of smaller image formats.
