ConEmu / Cmder support?

[nickolay]

https://conemu.github.io/ is a popular terminal replacement on Windows, which works by hiding the "real console" and re-rendering its contents in a ConEmu window.

ConEmu lets the user set up color schemes, which are applied when drawing to the ConEmu window, so termbg does not detect them, reporting the color of the "real console" instead. Same goes for Cmder, which relies on ConEmu under the hood.

Since ConEmu already has some support for xterm codes, we would probably need ConEmu to add support for querying the color scheme, similarly to microsoft/terminal#3718.

In the meantime, could it be added to the "unsupported" list in the README?

I added to the list.
