TCP client sensor data Android viewer

F.i., ESP32 or Pi Pico board serves as a TCP server, Android - as a TCP client. The server streams binary data - magnetic field - and Android displays it.

To be as simple as possible, it's assumed that the input binary stream is a 1-dimensional stream of raw data points (see "Supported binary data types" below). The value of received data points is displayed on the Y axis, and the point counter - on the X axis.
