feat: add dedicated topics support for MQTT configuration

[olegbilovus]

Add the option to publish each sensor on a different MQTT topic.

Some MQTT Dashboard applications such as IoT MQTT Panel do not support to filter the data by the values inside the message and to work properly, they need that the data is published on different topics.

When the option is enabled, it will publish to android/sensor/{sensorEvent.type}.
E.g.: The Magnetometer sensor will publish to android/sensor/android.sensor.magnetic_field

TODO: the Settings screenshot in the README.md should be updated.

Some additional tasks need to be completed:

1. When the user enables dedicated topics, the sensor list screen should be updated accordingly. For example, type = android.sensor.accelerometer should be replaced with topic = android/sensor/accelerometer.

2. When dedicated topics are enabled, the payload should no longer include the type field.

Some additional tasks need to be completed:

1. When the user enables **dedicated topics**, the sensor list screen should be updated accordingly. For example, `type = android.sensor.accelerometer` should be replaced with `topic = android/sensor/accelerometer`.

2. When dedicated topics are enabled, the payload should no longer include the `type` field.

I removed the "type" from the json and added the "topic" to the sensors lists when Dedicated Topic is enabled

Let me test it !

The app is crashing on changing topic as you haven't merged #3 in this branch

Edit: Okay no need to do this, it will be fine when i merge this into main

I merged main into this branch to be sure it still works also with the new dependency updates and to test the topic change without crashing the app.

Without closing the app, if you use topic 1, connect, disconnect and then change to topic 2 and connect again, look at the mqtt messages, you will more easily the Issue #1 where it will send messages also to the old topic.

Yes i noticed that issue. I am debugging the app to find the cause !
