Adds a new extension method IAnsiConsole.WriteAnsi that writes
VT/ANSI control codes to the console. If VT/ANSI control codes are
not supported, nothing will be written.
* Moves ColorSystem from Profile to Capabilities
* Renames Tty to IsTerminal
* Adds IAnsiConsoleOutput to make output more flexible
Closes#343Closes#359Closes#369
1. Add an ED3 command to clear the scroll buffer.
This command is not in the original ANSI terminal control sequences but
was added later to XTerm to account for the fact that most modern
terminals have a scroll-buffer.

This command is now awailable in basically
all terminals with scroll-buffers
2. Change CUP coordinates to 1, 1
The coordinates 0, 0 also worked, but strictly speaking they are outside
the available screen area and are capped to 1, 1 anyways.
This commit fixes#337
This makes it possible for encoders to output better representation
of the actual objects instead of working with chopped up segments.
* IAnsiConsole.Write now takes an IRenderable instead of segments
* Calculating cell width does no longer require a render context
* Removed RenderContext.LegacyConsole
* Removed RenderContext.Encoding
* Added Capabilities.Unicode
