Support ANSI color escape codes in the output buffer

[xaderfos]

For now this purely related to ruxnasm. It's output looks like garbage without support for color codes.
Adding this kind of support is not trivial but it looks doable. Some solutions seem to encode the buffer once the process has finished but that should be avoided. Ideally we need a buffer set up with color codes support out of the box to which we append the output of the assemblers and the emulator.
