Functions: don't display osascript call (#14)

* Functions: don't display osascript call

useful with something like:
__fish_apple_touchbar_bind_key 7 '╂ split' 'osascript -e "tell application \"System Events\" to key code 2 using command down"' '-s'

* Functions: Use guard clauses and long-format opts

Use --quiet instead of - q to improve readability.
Refactor nested if-else statements using guard clauses to reduce code complexity.

* Functions: Add missing return in bind key func
