feat: allow fingerprint matching based on instance of

Issue

Currently, method fingerprints match using exact class match (or more specifically, 'starts with' matching of a class name). It does not allow polymorphic matching, such as comparing what the class is an instance of.

For example. A target method takes a two obfuscated parameters: private void a(Lfoo;Lbar;)

Currently it is only possible to match this method by specifying a signature with 2 parameters of any kind of objects:

MethodFingerprint(
parameters = listOf("L", "L")

But looking a these classes we see that:

Lfoo; extends Ljava/lang/Enum;
Lbar; implements Ljava/util/map;

So the method signature should allow specifying an 'instance of' like comparison. Perhaps this can be done by specifying a prefix to the class name: parameters = listOf("instanceof:Ljava/lang/Enum;", "instanceof:Ljava/util/map;")

This same logic could be used for the return type as well: returnType = "instanceof:Ljava/util/list;"

Feature

add polymorphic matching to method signatures.

Motivation

Allow better signature matching
