Hidding directories in ISO

[d1zanv]

Problem

As mentionned in the issues #13, it is not possible to hide directories using the flag --hide or --backdoor.

Solution

ChoiSG, who added the functionnality to hide files, used the function set_hidden.
After reviewing how was working the function, I discover that it was possible to hide directories as well with the same function.

First things I did was to add a condition to check, with a regex, if a path contain an extension.

if re.match(r'.+\..+', hideItem):

If there is, the code of ChoiSG do his job.

if re.match(r'.+\..+', hideItem):
    self.logger.text(f'\tHiding file: //{hideItem}')  
    iso2.set_hidden(joliet_path=f'/{hideItem};1')

And, if there is no extension, I consider it is a directory and use almost the same code as for file, except I get rid of the ;1.

else:  
   self.logger.text(f'\tHiding dir : //{hideItem}')  
   iso2.set_hidden(joliet_path=f'/{hideItem}')

At the end, the library which contain the function set_hidden check if the file or directory exist, it then resolve the possible problem of path which are not file or directory.

Feel free to tell me if I've made any mistakes in my code or if there are better ways to do it. I made this modification quickly for a personal project and it worked for me, so I thought I'd share it with the community.
