task/WG-170: fix scraping of questionnaire

[nathanfranklin]

Overview:

This PR adds support the scraping of questionnaires. It ensures the questionnaires in connected projects are scraped and that any asset images aren't inadvertently scrapped twice.

This PR also:

• refactors how we determine which files to scrape
• removes audio file formats that were not used

Related Jira tickets:

• WG-170

Summary of Changes:

Testing Steps:

1. Use hazmapper's feature/questionnaire when running hazmapper
2. Create a new map and select top level dir of shared project "Questionnaire_Example". ensure "Sync Folder" is checked. (See screenshot below)
3. Click "Submit"
4. See that one questionnaire is imported correctly. and that its asset images aren't incorrectly imported as individual assets.
5. Note that there will be some log errors as there are some questionnaire files in the /Rapp folder that do not have a geolocation. I can remove those if we want a cleaner project to test thing with.
