[Feature Request] Add RGB565 option

[krizkontrolz]

Hi Martin, Are you planning to, or would you consider, adding a feature to be able to show the RGB565 (16-bit) color code (both Hex and Decimal)? There are separate tools for doing this (e.g., http://www.barth-dev.de/online/rgb565-color-picker/), but it would be useful to have all options in one color picker (especially the picker that is already part of PowerTools). Regards, Kriz
