fix ASMRemapperTransformer

[danyadev]

fixes #69 (nice)

1. changed class reader & writer flags back to COMPUTE_MAXS & EXPAND_FRAMES, which fixes the main issue
2. switched from ClassConstantPoolParser to my own BytePatternMatcher, which allows to match substrings, and started searching for substrings with asm package paths instead of matching only entries which start from these paths. I.e. now we can match Lorg/objectweb/asm/tree/ClassNode; arguments inside method signatures. Just in case someone creates a method with a specific ASM package in arguments instead of the default org.objectweb.asm one. Because if we won't replace them we won't be able to pass our desired ASM package. That was the default behavior before my initial PR either way
