Suppor for I2C Based motor controller

**Describe the problem you have/What new integration you would like**
I would like some kind of support for some kind of I2C based motor driver like the WEMOS D1 MINI MOTOR DRIVE SHIELD.

**Please describe your use case for this integration and alternatives you've tried:**
I have used this motor driver for roller blind controllers and as they use the I2C bus it saves pins, is small and cheap. In my use case i control 4 motors, with a traditional motor driver i would need a minimum of 8 pins, this way i only require 2.

**Additional context**
A arduino library for this already exists [here](https://github.com/wemos/LOLIN_I2C_MOTOR_Library), but I've had no luck getting it to work with esphome (lack of knowledge on my part i believe)
