Set title mode escape codes not matched

[cancerberoSgx]

Hello,

according to links below, the following sequence instruct the terminal to set window title and icon:

\u001b]0;sg@tota:~/git/\u0007

and strip-ansi is not removing it

In other words I expect

stripAnsi('\u001b]0;sg@tota:~/git/\u0007\u001b[01;32m[sg@tota\u001b[01;37m misc-tests\u001b[01;32m]$') 

to return the string:

[sg@tota misc-tests]$

This is very common in xterm based linux stdout to print the prompt. Thanks BTW this is great project! keep it up!
