Modify extension bytecode to fix SimpleDateFormat cannot parse errors

[Syer10]

This PR fixes unparsable date errors, such as the ones from NHentai, by doing this process:

1. Waits for Dex2Jar to decode the apk into a valid Jar file
2. Loads all classes in the Jar file as ByteArrays
3. Uses Java ASM to read the ByteArrays as Bytecode
4. Changes all references from java.text.SimpleDateFormat to xyz.nulldev.androidcompat.replace.SimpleDateFormat
5. Writes the new Bytecode as ByteArrays
6. Loads all non-class files from the Jar
7. Writes the new Jar into the same place it loaded from
