Does not handle CR LF with a color change in between appropriately

[RLievaart]

As I found out the very hard way (half of my output not showing and an hour of debugging), some programs throw a color change in their output between a CR and a LF. I.e. [CR][ESC][31m[LF]

AnsiToHtmlConverter.php erases a line followd by [CR][color change][LF] since it thinks the color change is text at the beginning of a new line so it "overwrites" (deletes) the old line. It isn't Terminals like Putty will handle this correctly.

Proposed fix: for me this change in AnsiToHtmlConverter.php (line 50) worked.

$text = preg_replace('#^.*\r((\x9B|\x1B\[)[0-?]*[ -\/]*[@-~])*(?!\n)#ms', '', $text);

Probably the regex can be a bit simpler (I included all ANSI codes in the regex, that's overkill. I took it from https://stackoverflow.com/questions/14693701/how-can-i-remove-the-ansi-escape-sequences-from-a-string-in-python#33925425 ).
