Poetry Is Awesome

And not just the Will Shakespeare kind. Switched from using setup.py to poetry to manage package details. The source was reorganized a little bit to accommodate the change; src/blynclight had the src portion of the path elided. Additionally, four of the scripts in contrib were moved into the package ( blynclight/scripts/... ) and given click command-line interfaces. These four are now installed when the package is installed:

• blync: basic access to light attributes
• fli : flash lights impressively
• rainbow: smoothly transition color in a rainbow pattern
• throbber: varies color intensity over time

Docs are still a little sketchy for the command-line interfaces, expect updates over time.
