Detect exits when recipe does not contain filters

[mjcbello]

Hi @vsoch ,

I've been working with @wetzelj on our internal deid pipeline project. It has been really interesting working with all things DICOM and pydicom/deid. Thank you for your contributions!

During my testing, I noticed that calling detect on the DicomCleaner results in a bot.exit() if the current recipe file does not contain any filter sections. Is this the intended behavior of the application? Any objections to returning flagged=False instead of sys.exit?

detect.py lines 124-127:

    # Load criteria (actions) for flagging
    filters = deid.get_filters()
    if not filters:
        bot.exit("Deid provided does not have %filter, exiting.")

Definitely not! It would be good to, in addition to adding the return, print a clear message for the user (debug or info, up to you!)

Sounds good! I have a fix ready. Would you like me to submit a pull request against the currently opened pull request #154 or a new pull request against master?

It would be easier to package it in the same version as #154 - and if you have bandwidth and are able, a review of the PR would be helpful! Sometimes users open issues and then there is a fix but they never come back to review, even if things are ready to go. So your review would be greatly appreciated!

And wow, I'm honored you opened your first issue here! Open source is a lot of fun, welcome to GitHub!
