Wemos motor Shield (TB6612NFG)

**Describe the problem you have/What new integration you would like**

I have some Wemos motor shield and I would like use for driving a fan. It's an I2C controler.
I've tried to using custom component without success.
the library using is : https://github.com/wemos/LOLIN_I2C_MOTOR_Library
Thanks a lot.

**Please describe your use case for this integration and alternatives you've tried:**

**Additional context**

Start by reviewing the linked LOLIN_I2C_MOTOR_Library and the issue's description of the Wemos motor shield, TB6612NFG, and I2C control. Determine the required integration scope and compare it with the unsuccessful custom-component attempt; done should mean the shield can drive the requested fan through the project.
