Add parameter for exact file matching since file filter uses multiple word matching

[seanwo]

Love the tool and the robust features for retries and multi-part downloads. I had to alter it to do exact file matching to pull an exact file out of an item library. I think the issue is that the files I was trying to pull had spaces in them.

Example usage:

python3 ia_downloader.py download --verify --resume --split 5 -i ialibraryname -f "filename with multiple spaces.zip"

When you use the file filter parameter it tries to match on very word even if you put it in quotes. Since I just want one file at I had to hack it to do an exact match for the file filter. Maybe it would be nice to have an officially supported command line parameter for exact matching? I would put a pull request in but I am not sure what makes sense for the addition. Ideas are welcome and if I have time I could throw something together. Below is the patch I used to get my job done.
