Description

This is code to add support for INA237, from @ghcoleman who is working at Grobotic Systems. The code has been tested and works, but I do not have access to the testing environment.

I realise the PR is a bit bare and perhaps based on a version that isn't main. I definitely do not expect it to be merged as is, but I submitted it as it might be useful to someone in the future, for example the author of issue #78.

Fixes #78
