If an application runs on Windows 10.0.15063 or above, on a
runtime prior to net5.0, the color system detection will fail
and fall back to 8-bit color support.
The reason for this is because the behavior of
Environment.OSVersion.Version differs between runtimes. Unless you're
running on net5.0, both the major and build version components will
not reflect those in the actual Windows version.
1. Update CSI constant to include the [ character.
See ECMA-48 Section 8.3.16
https://www.ecma-international.org/wp-content/uploads/ECMA-48_5th_edition_june_1991.pdf
2. Use string interpolation, because it's easier to read
(and internally uses a StringBuilder)
3. Add ESC constant, because the AnsiBuilder needs it to create links.
4. Remove unused SGR overload.
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.

The RegEx runtime perf was never anything noticeable - it was the startup time that was eating over a third of time during initialization.
This shaves 200ms off the startup time.
This commit also changes the behavior of ProgressContext.IsFinished.
Only tasks that have been started will be taken into consideration,
and not indeterminate tasks.
Closes#329Closes#331
The 'root' variable does not exist in current context. Either should call Render(tree) or have it renamed to root. I've chosen root as it's more consistent with the examples later on.
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
These methods don't require a string.format call so we'll directly call the Render method without a call to string.format.
Added bonus of a a couple fewer allocations too.
Makes the Report method an explicit implementation to allow for better interoperability with standard .NET progress functionality while keeping backwards compatibility with existing ProgressTask functionality.
Closes#285
Previous behavior was that the only way to get a task to a finished state was to artificially set the Value to MaxValue.
With this change StopTask() will also complete the task with the change that a task cannot be restarted.
In both of these loops context is captured preventing caching of the lambda. this results in a pretty significant amount of allocations especially with progress bars that constantly are remeasuring
