Update readme and gitignore for better mac usabilty
Background / User story
A small update to the gitignore and readme to include mac issues
.gitignore
- autogenerated .DS_Store files are the scourge of the mac world and we do not need to commit them
README
- though the node version is technically semver accurate, it can often be assumed that it means "anything node 16+". as this is not the case I have added a specific warning about this
- on the macs that have an m1 processor it's all broken, but adding the architecture is an easy fix. This includes a specific warning and fix for that
What to change
