Description
Added the OneWire-Test. Therefore, 3 tests are executed:

1. Is there a device connected?
2. Does the Master receives the description of the slave?
3. Does the Master receives the data?

Related Issue

1. Issue: The OneWire-Library is not working. Therefore, the test was developed with an Arduino Mega 2560
2. Issue: We cannot set a board as slave. Therefore I used DS18B20 as a slave.

Pull Request Overview

This pull request adds tests for the OneWire sensor by introducing new test cases and supporting build targets for verifying device connection, chip description, and data retrieval.

• Added a preprocessor block in the main test file to run onewire sensor tests.
• Created a new test file with three test cases for OneWire sensor functionality.
• Updated the Makefile to include a target for the OneWire sensor tests.

[nitpick] Consider defining a named constant for the OneWire bus pin instead of using the hard-coded value (5) to enhance code readability and ease future modifications.

Suggested change

	// OneWire instance and variables
	static OneWire oneWire(5); // Pin 5 is used for the OneWire bus
	// Define the pin used for the OneWire bus
	constexpr int ONE_WIRE_BUS_PIN = 5;
	// OneWire instance and variables
	static OneWire oneWire(ONE_WIRE_BUS_PIN); // Use named constant for the OneWire bus pin
