Deps clash

When trying to build on macOS 10.15.4 I get this:

error: multiple packages link to native library `clang`, but a native library can be linked only once

that is an interesting problem!
I'll have to do some research on how to resolve.
Thanks for the heads up

The problem is that the audio part off ggez dependencies for mac are not updated.
As audio is not used in this project, and the ui logic can be simplifed, take a look at this PR. It removes ggez and imgui in favor of a simple framebuffer.
