* Supports ASRC with null renamed package.
* Rework ASRC Chunk parser to a loop to break assumption of order of chunks
* Break out unknown skips for alignment to ResourceTypes.h
* Add verbose information for file skips
* Add test for protected apk sample
* Rework chunk parsing for StringBlock
* Refactor AXML Parser to support proper header reading
* Fix parsing if attribute size reported does not align to actual size
