😱 Fix screen capture (again) (#70)

#### Summary:
- `with_wireless_download` wrapper no longer suppresses the return value of the wrapped function
- Also snuck in a change to prompt the user to confirm when reading a file wirelessly if it's big

#### Motivation:
- It broke (again)

#### Test Plan:
- [X] Screen capture works again both wired and wirelessly
- [X] See confirmation to download screen capture wirelessly

#### Commits:
* Fix screen capture (again)

* upload -> download

* upload -> download the right string
