[feature] Kotlin Metadata annotation deobfuscation enhancment

[yaroslavyadrov]

Sometimes Kotlin Metadata annotation stays in .dex files due to bad obfuscation. It seems like this annotation contains package and class names in extraString parameter.
Maybe it will be useful to use them for better deobfuscation?

@yaroslavyadrov sure, this will be a nice feature.
Also, Kotlin often inserts null checks with names for method arguments.

I would like to add that Kotlin is usually very useful in regards with reverse engineering not just for null checks, which are sometimes very vague but more with toString, which is often implemented by Kotlin-s compiler and offers very easy to read (at least for a human) bindings between the original name and the obfuscated name.

So, I'll try to implement this in a couple of weeks or so then
