Fix invalid filenames

[tetrahedrl]

Hey, this looks like it solved the issue on my end.

• Method cleanPath takes a path string and returns one where invalid characters are replaced with -
• Wraps creation of File object referring to destination and the extraction in a try block, catches InvalidPathException.

I only tested that this worked for exporting my SMS attachments from the Files tab, where it worked just fine and exported all 20gbs of them. Did not test exporting by domain or search.

This might be a better way to handle it, up to you. Tries without any replacements, if there's an issue, does the replacements and logs it, if there's still an error, then throws an exception. Also realized drive letter isn't included until later, so no need to ignore first two characters.

No problem!
