SciFi v4 decoding to v6 logic
SciFi v4 decoding is replaced by v6 logic/code where applicable. Main reason for this change is to allow easier maintenance of the code and preparing decision logic to switch between v4 and v6 based on the input data as done in the UT code.
v4 DirectDecoder is removed as it is not needed and useful when using v6 logic.
