fix: decoding APK with many compact entries and unknown uses-sdk attrs (#3705)
* fix: decoding APK with many compact entries and unknown uses-sdk attrs

This fixes 2 new issues with a stock APK sourced from an Android 15 ROM.

1) mIn.readShort() for size in readEntryData is incorrect and the size < 0 check is not possible.
   Entry size is stored by AAPT2 as an unsigned short and thus will never be negative.
   Reading it as a signed short will cause negative entry sizes in compactly packed entries in
   very large string pools and will result in a lot of "APKTOOL_DUMMYVAL_" values.

2) sdkInfo isn't stored properly for APKs with unexpected properties in uses-sdk tag.
   As far as I can tell, these attributes serve no purpose and can be ignored.
   In the given APK, additional "android:versionCode" and "android:versionName" attributes appear
   in the uses-sdk tag, purpose unknown and they don't represent the actual version of the app.

   E: uses-sdk (line=26)
     A: http://schemas.android.com/apk/res/android:minSdkVersion(0x0101020c)=35
     A: http://schemas.android.com/apk/res/android:versionCode(0x0101021b)=31
     A: http://schemas.android.com/apk/res/android:versionName(0x0101021c)="3.1"
     A: http://schemas.android.com/apk/res/android:targetSdkVersion(0x01010270)=35

* test: add assertion for issue 3705
