Add DHT11 interface and UART integration for ultrasonic sensor project

- Created DHT11 interface in Verilog to handle communication with DHT11 sensor.
- Implemented LED control logic to indicate sensor status and data readiness.
- Added project scripts for building, cleaning, and simulating the design.
- Established constraints for FPGA pin assignments.
- Developed testbench for DHT11 UART communication.
- Updated README files to reflect project functionality and commands.
