Add in file copying and renaming sanitisation in python scripts

[M-Davies]

Right now, if you try to upload a file called 20210301_120317(0).jpg it won't be expanded. I am unsure of the consequences of this but the path does result in being 20210301_120317\(0\).jpg to escape the brackets (and that's without considering the effect of files with spaces). As a result, we should sanitise or at least warn the user about these issues
