Update 1.1.8b

This update fixes a bunch of smaller issues.

- The progress completion display on the mission screen is now per-mission-difficulty rather than global.
- Added game completion percent, the number of medals, and bonus objectives to the help narration on the mission screen.
- Added more controls information to the help narration in arcade mode.
- Removed the warning from the Audible Cues 1 mode selection.
- Adjusted the call-and-response sections on Komodo so that the Rush Delivery mission bonus objective is possible.
- Removed the "show ghosts" option from the race menu in itch.io builds.
- Fixed the power increase sound playing when boost is not unlocked.
- Narrate power max when power is gained via holds or mind tap.
- Narrate some race statistics when pausing the game.  They can also be narrated at any time by pressing F1 or clicking the right stick.
- Many small narration fixes and improvements.
