Remove call to i2c.start()

[dquadros]

As far as I can see in the docs, the start() method has always been a "primitive method" that sends a start bit and it is not needed in the context (the rest of the code uses "memory operation" methods that will send start bits as necessary).

Since v1.10 the start method is only available on software I2C, so you will get an error if you use this library with the current version of MicroPython using hardware I2C (probably the most common use).

Use this lib - it works OK on ESP32:
