Description
**Describe the problem you have/What new integration you would like**
Widely used ultrasonic ranging sensors like US-100, JSN-SR04T etc. can work in a serial port mode (Mode2 and 3) which seems to be more precise and less resource consuming but this mode is not implemented in ESPHome (only Mode1 "HC-SR04" supported). Can you please add it?
**Please describe your use case for this integration and alternatives you've tried:**
**Additional context**

Research direction
Begin at ESPHome's ultrasonic distance sensor component and trace the existing HC-SR04 Mode1 support. Research the serial-port protocols used by US-100 and JSN-SR04T for Modes 2 and 3, then define tests and acceptance criteria for supporting those modes with the stated precision and resource benefits.
