Appium workaround for setLocation errors

Versions of Appium above v1.9.1 and below v1.16.0 have a bug in `setLocation` and `getLocation` that looks like this:

```

```

The workaround for this is to add this snippet of code:

```python
def updateSettingsApp():
    # Get rid of the broken io.appium.settings apk
    driver.remove_app('io.appium.settings');
    
    # Install the patched io.appium.settings apk
    driver.install_app('https://github.com/appium/io.appium.settings/releases/download/v2.16.2/settings_apk-debug.apk')
    
    # Set the permissions on the app to allow location services
    driver.execute_script('mobile: shell', {
        'command': 'pm',
        'args': ['grant', 'io.appium.settings', 'android.permission.ACCESS_COARSE_LOCATION'],
        'includeStderr': True,
        'timeout': 5000
    })
    driver.execute_script('mobile: shell', {
        'command': 'pm',
        'args': ['grant', 'io.appium.settings', 'android.permission.ACCESS_FINE_LOCATION'],
        'includeStderr': True,
        'timeout': 5000
    })
```

And call `updateSettingsApp` after session is initialized (and before any call to `getLocation` or `setLocation`).

The snippet is written in Python but can be adapted to any other Appium client languages. Just look for documentation for:

* [Remove App](http://appium.io/docs/en/commands/device/app/remove-app/)
* [Install App](http://appium.io/docs/en/commands/device/app/install-app/)
* [Execute Script](http://appium.io/docs/en/commands/mobile-command/)

This workaround is unnecessary for Appium 1.16.0 and above as it will already have the patched settings app.
