feat: support multi-dex containers

[IgorEisberg]

• Preload the APK file as a ZipDexContainer once per SmaliDecoder instance and reuse it for all decode calls.
• Defer smali folder naming. SmaliDecoder will decide folder naming based on whether a dex file is a multi-dex container or not.
• If a dex file is a multi-dex container, each contained dex file will be decoded to a separate smali folder.
• Since smali support for dex version 041 is limited, building smali folders decoded from a multi-dex container will produce separate dex 039 files instead.
