Readme circup install instructions typo

[somenice]

Small issue on readme
I believe it should read circup install adafruit_connection_manager
instead of circup install adafruit_connectionmanager

[somenice]

Nevermind, looks like it works either way.

Searching for dependencies for: ['adafruit_connectionmanager']
Ready to install: ['adafruit_connection_manager']

'adafruit_connection_manager' is already installed

It is a typo, since only import adafruit_connection_manager is correct. But the name matching in circup is forgiving. Reopening to fix.
