Ole-Morten Duesund e8428de775 Add progressive web app companion for cross-platform access
Vite + TypeScript PWA that mirrors the Android app's core features:
- Pre-processed shelter data (build-time UTM33N→WGS84 conversion)
- Leaflet map with shelter markers, user location, and offline tiles
- Canvas compass arrow (ported from DirectionArrowView.kt)
- IndexedDB shelter cache with 7-day staleness check
- Service worker with CacheFirst tiles and precached app shell
- i18n for en, nb, nn (ported from Android strings.xml)
- iOS/Android compass handling with low-pass filter
- Respects user map interaction (no auto-snap on pan/zoom)
- Build revision cache-breaker for reliable SW updates

Get the `byteOffset` out of a DataView, robustly.
This will work in node <= 0.10 and < 0.11.4, where there's no prototype accessor, only a nonconfigurable own property.
It will also work in modern engines where `DataView.prototype.byteOffset` has been deleted after this module has loaded.
## Example
```js
const dataViewByteOffset = require('data-view-byte-offset');
const assert = require('assert');
const ab = new ArrayBuffer(42);
const dv = new DataView(ab, 2);
assert.equal(dataViewByteOffset(dv), 2);
```
## Tests
Simply clone the repo, `npm install`, and run `npm test`
