Fixed broken color latex segments in README table

Replaced them with images generated by an image placeholder service (https://placehold.co/) for now. Not ideal, but looks nice.

 Note that within the _"Microlepidoptera"_, the group naming and color coding mostly does not represent actual monophyletic entities, but is purely for aesthetics and practical reasons. The _"Macrolepidopterans"_ are, on the other hand, divided into four strictly monophyletic groups here, that actually do make somewhat sense from a practical standpoint.
