OSC hyperlinks do not work with spaces

OSC hyperlinks do not work when the text includes spaces.

> const AnsiUp = require('ansi_up'); 

> const ansi = new AnsiUp.default;

> ansi.ansi_to_html('\x1B]8;;http://www.google.com\x07bb\x1B]8;;\x07')
'<a href="http://www.google.com">bb</a>'

> ansi.ansi_to_html('\x1B]8;;http://www.google.com\x07b b\x1B]8;;\x07')
']8;;http://www.google.com\x07b b'

I think I had a reason for this, but now I cannot remember. I will review this today.

Ok - yeah, I will fix this. Thanks.
I think I half copy pasta'd the previous portion of the regex and half avoided the all whitespace anchor text problem. There was a little ambiguity In the spec by egmontkob, wrt handling incomplete OSC URL packets in the buffer. Regardless, having space there totally makes sense.
