RGB colors are not translated correctly

[sedrubal]

Using this example file: cyan.txt

$ cat cyan.txt | ansi2html --inline

Produces a random color and does not use the original one (cyan #9bf6ff):

<span style="color: #afff5f">I am cyan (#9bf6ff)</span>

For latex the same wrong color is used:

cat tmp | ansi2html --inline --latex

\textcolor[HTML]{afff5f}{I am cyan (#9bf6ff)}

This is a duplicate of #101. Ansi2html currently does not support truecolor codes. I'd suggest closing this issue in favor of #101.
