Flag of Latvia: incorrect proportions and colour

[jbasko]

Hello! This is quite a neat looking library, but it appears that the flag of my home country Latvia is not particularly accurate. It appears to use the same red as that in the flags of Austria and Lithuania, but that is incorrect, also the proportions of the widths of the white and red bands seem to be off.

The Wikipedia page is actually quite accurate: https://en.wikipedia.org/wiki/Flag_of_Latvia

To fix:

1. the white band should be exactly half the width of the red band. 2:1:2.
2. the color should be carmine red (dark red). The colour visible on this page at least on my screen seems correct: https://en.wikipedia.org/wiki/Carmine_(color)
