I created a new, mostly over complicated, filename parser
The new parser works well in many cases and will collect more data than
the original parser but will sometimes give odd results because of how
complicated it has been made e.g.
'100 page giant' will cause issues however '100-page giant' will not
Remove the parse scan info setting as it was not respected in many cases
