/*
Read args from a config file:
- allows use of more interesting args w/o risk of checking them in by mistake
- allows use of different args w/o rebuilding the app
- uses compiled in defaults if config file missing or broken

Example android-config.json:
```
{
  "args": [
    "--npub",
    "npub1h50pnxqw9jg7dhr906fvy4mze2yzawf895jhnc3p7qmljdugm6gsrurqev",
    "-c",
    "contacts",
    "-c",
    "notifications"
  ]
}
```

Install/update android-config.json with:
```
adb push android-config.json /sdcard/Android/data/com.damus.app/files/android-config.json
```

Using internal storage would be better but it seems hard to get the config file onto
the device ...
