Add asset bootstrap script and base64 encoded assets

[nbschultz97]

Summary

• add scripts/bootstrap_assets.py to decode base64-encoded model and PNG icons into app asset locations
• store rotor model and icon binaries as base64 text under assets/
• document bootstrapping step in README and new USAGE guide

Testing

• python3 scripts/bootstrap_assets.py
• python3 -m py_compile scripts/bootstrap_assets.py

Codex Review: Here are some suggestions.

DroneDetectAndroid/.gitignore

Line 2 in 4fdfe3d

app/

[P1] Stop ignoring entire app module

.gitignore currently ignores the root app/ directory to avoid committing generated assets, but that rule also hides every source file for the Android module (Gradle scripts, manifests, Kotlin/Java, etc.) from version control. Once real app code is added or modified, git status will never surface the changes, making it impossible to commit or review the core application. Limit the ignore pattern to the generated asset subdirectories (e.g. app/src/main/assets and app/src/main/res/drawable) so that code remains tracked while binaries stay out of Git.

[P1] Provide real base64 for rotor model

The file assets/rotor_v1.tflite.b64 decodes to the ASCII string "rotor model placeholder" (22 bytes) rather than a TensorFlow Lite binary. After running bootstrap_assets.py, the generated rotor_v1.tflite will not be a valid model, so any code that tries to load it will immediately fail at runtime. Replace this placeholder with the actual base64 of the TFLite model or document that the user must supply it, otherwise the bootstrapping step cannot produce working assets.
