T8b949e/**

* Converts route CoT XML (b-m-r) into ATAK-importable KML data packages.

*

* ATAK silently ignores route CoT events received over TCP streaming connections — it only accepts routes from KML/GPX

* file import, TAK Server mission sync, or data packages auto-imported from the monitored directory

* `/sdcard/atak/tools/datapackage/`. This generator bridges the gap by extracting waypoints from the SDK-reconstructed

* route XML and packaging them as a KML LineString inside a MissionPackageManifest v2 zip.
