Support for Adafruit MSA301/MSA311 Accelerometer

[lboue]

Describe the problem you have/What new integration you would like Add support for Adafruit MSA301/MSA311 Accelerometer in ESPHome

The MSA311 is a super small and low-cost triple-axis accelerometer. It's inexpensive, but has just about every 'extra' you'd want in an accelerometer:

• Three-axis sensing, 14-bit resolution
• ±2g/±4g/±8g/±16g selectable scaling
• I2C interface on fixed I2C address 0x62
• Interrupt output
• Multiple data rate options 1 Hz to 500 Hz
• As low as 2uA current draw in low power mode (just the chip itself, not including any supporting circuitry)
• Tap, Double-tap, orientation & freefall detection

The MSA311 is very similar to the MSA301, but is not a drop-in replacement. The I2C address has changed from 0x26 to 0x62!

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

Arduino library

• Adafruit_MSA301

CircuitPython library

• Add MSA311 support

It's perfect. The level of detail is impressive. So it's very easy to understand.
