Maintenance: Improve Multiple File Download Collision Formatting

[marofke]

Description

Currently, if you download your output on top of an existing download and use the CREATE_COPY option (i.e. you get colliding files), it appends " (1)" to the file name, over and over.

So if you download repeatedly, you could have a file like "output (1) (1) (1) (1) (1).png" which makes file names unnecessarily long.

Solution

Ideally, we increment a number to the file name for any collisions when using the CREATE_COPY option when downloading outputs. That is, if we have a file named "output.png", downloading it multiple times would create new files called "output (1).png", "output (2).png", etc.
