Fix incorrect blue color on radar for diwako_dui_colors >> tritanomaly

[pennyworth12345]

When using the tritanomaly color scheme the blue icon on the radar is colored differently than the blue text. If you assign a unit to the blue team and get the compass color assigned to the unit ( _unit getVariable "diwako_dui_main_compass_color") it returns [0.2,0.411765,-0.0235294].

The blue config hex value for diwako_dui_colors >> tritanomaly contains a lowercase 'd'. This causes an issue with _getColorFromHex when converting from hex to an RGB value in the range of [0, 1] because the function expects the incoming hex string to only have values 0-9 or A-F. The 'd' cannot be found in _nums and thus _b = -1 * 16 + 10 == -6, and then divided by 255 to produce the value -0.0235294. The negative value is then treated as zero when used by drawIcon3D.

These changes fix the aforementioned config value and adds toUpper to _getColorFromHex, in case a lowercase letter slips into another hex value in the future.

Oh that is a good catch
