Add DCT decompression config methods in favor of compile-time changes
...
As a rule, we should avoid conditional compilation is it always causes
code paths that are sometimes not even seen lexically by the compiler.
Also, we want the actual code being fuzzed to be as close as possible
to the real code. Conditional compilation is suitable to handle
underlying system differences.
Instead, favor configuration using callbacks or other methods that can
be triggered in the places where they need to be exercised.
