Revert "twi_stop() should use the same timeout as everywhere else"

This reverts commit 68fe5f1dae1bb41183bb37eeda3fb453394a580c.

rename timeout function for improved clarity

- resetting the twi interface on timeouts is now optional
- timeouts in the ISR are no longer hardcoded and now obey the set timeout value
- a user-readable flag is now set whenever a timeout occurs
  - the user can clear this flag whenever they like
