HX711 via I2C (m5stack)

**Describe the problem you have/What new integration you would like**
Support HX711 sensors via I2C.

**Please describe your use case for this integration and alternatives you've tried:**
I currently use a lot of m5stack ESP32 gear, and would like to use the m5stack HX711 (along with other sensors) which uses I2C. At present, the HX711 sensor requires dout_pin and clk_pin. I've looked to see if I can directly use arduino code, but this is a messy workaround and I'd prefer to keep to native ESPHome if possible.

**Additional context**
I'm new (and very amateur) with ESPHome, so if I'm missing something obvious please let me know!
