Reducing number of dependencies #95
Description
We are using asciimatics with an embedded device and it requires lots of dependencies. The main offender is Pillow which also requires 3-6 other dependencies and some of them do not compile very well for anything other than basic i386/amd64 platforms. I also noticed that sub dependencies are some sort of imaging libraries for jpeg and png and I can hardly imagine they have anything to do with TUI library. So, would it be possible to remove dependency on Pillow and revisit other dependencies as well.
