fix: support COMPACT/OFFSET16 packed resources.

[iBotPeaches]

fixes #3367 && fixes #3366

---

• read entry data - support flag/size difference
• set res values - split regular/compact/complex
• set entry data - dig into specNamesId for compact set
• read entry - prevent assuming specNamesId for compact resources
• offset16 parsing - properly calculate offsets for offset16 resources
• tests - add sample with both offset16 and compact resources

Sample can be found here for tool authors who stumble on this - https://github.com/iBotPeaches/TestApks/tree/master/Issue3366

You need more than 1 string entry to trigger the inclusion of some of these optimizations. So this packs my test application to 1000+ strings (and only strings) and it appears to be a valid OFFSET16/COMPACT app.
