Integrate Qwiic and Stemma

Problem environment

The Qwiic and Stemma peripheral connection standards are well documented and can be leveraged to extend features to the end user, such as easy pluggable connection to sensors and actuators.

Steps to reproduce

1. Observe the layout
2. Search for a Qwiic
3. Search for a Stemma

Expected result

Qwiic and Stemma interfaces and appropriate connectors exists and are documented.

Actual result

No Qwiic and Stemma interfaces exist, nor is there documentation describing them.

Severity level

This is low priority because project requirements do not include peripheral expansion.

There is neither board surface area nor project hours available for the resource intensive integration of peripheral expansion interfaces, so this bug report will not resolve.

Reopened after consideration of the very small footprint size. Reduce the notice silkscreen area taking space, and replace it with a I2C connector.
