Android: Replace TBXML with XmlPullParser

- The TBXML library produces a warning in Google Play Console that an app does not support 16 KB page sizes
- It's not necessary to use a third party library for parsing XML files, so it's not necessary to support that library still
- TBXML was used to read KML files
