Create a way to donate audio samples using a web form

On the plot form, add "donate audio sample". It uploads to a server (where?) and then opens a google form to add information to that sample:

- Speaker demographics
- Speaker accent / disabilities
- Intended word
- Intended vowel sound (make a huge dropdown)
- Contact information

Start by locating the plot form in the iOS app and reviewing how it handles audio samples. Clarify where uploads should be stored and how the Google Form should receive the sample information, including the listed demographic, speech, and contact fields. Done means the plot form can initiate an audio donation and the associated information is submitted successfully.
