Researcher viewable permission on other's studies.

# Narrative
When allowing researchers to filter their study from a participant, they'll need a list of studies. This list cannot show studies they're aren't meant to be seen, due to some studies are held from public participation on purpose. These non-public studies could contain sensitive materials.

# Acceptance Criteria
- [ ] If there's a permission that maps to "Studies I am allowed view"
- [ ] How to make one, if there's isn't one.
- [ ] A way to get a list of studies where the researcher has the "I am able to view" permission and all publicly "discoverable" studies.
