Brightness setting

[williambout]

It would be great to be able to setup the brightness when launching Gif2UnicornHat.
Like ./Gif2UnicornHat loop.gif 0.5

Yep, that's been on my todo list. Your request may motivate me to do it. :P

Alright, I threw something together. Give it a try and let me know if you have any problems.

[williambout]

Works perfectly. Thank you.
It would also be great if no parameters detected, to check a config file where you can set the brightness based on the hour of the day.
I don't have knowledge in C++, so I can't really help :/

I'd considered something to dim the display based on time, or maybe an ambient light sensor, since I have it running 24/7 in an office building.

I ended up rejecting that idea because it adds more complexity to the project than I was really willing to deal with.
