The black level obtained from the tuning file in software ISP is retrieved in init (because this is the standard algorithm method with access to tuning data) and stored into context. But the context gets reset in configure and the black level is lost and never applied. Let's store the black level from the tuning file into an algorithm instance variable and put it into the context only later in configure. This is similar to what rkisp1 IPA does with the values obtained from the tuning file.
