otoca: add cam hook, fix printer rotation (#573)

## Link to GitHub Issue or related Pull Request, if one exists
related to #154 though this PR doesn't fix it

## Description of change

1. Add an option for cam hook so that the game can be launched without
any camera
1. Rotate image printed out by print-to-file so that it's right side up
(portrait orientation)

## Testing
Able to boot the game without any cameras, and tested printing in test
menu.

"Holo" printing remains broken.
