OPAL type II tables use a 4 vector for composition, while many other opacity tables use a 2 vector of composition to index tables. In an attempt to be as general as possible I have updated the OPAT specification to allow for tables indexed by a vector of any length [1, 255]. This should allow a single spec to be used when storeing and accessing type I or type II tables.
BREAKING CHANGE: Careful thought will have to be given to how the C++ module handles this. We want the same code to work for querying data from any kind of opaticy table
