Add continous vibration for first triangle

 - There is a "Reset Alarm" button in the phone-side settings to help if you make an unsolvable alarm configuration by mistake.
 
 ## Some Neat Stuff
-- The vibration pattern is randomized. It derives the length of the three pulses from the angles in the generated triangle. Neat!
 - Some of the alarm scheduling code was taken from [Gentle Wake](https://github.com/SeaPea/GentleWake). It seems trusted by the community, so... I stole it! The beauty of open source, no AI needed!
 - A custom font was made to satisfy the need for something that looks like LECO but is monospaced. The version I made contains only numbers, period, and colon, but if you want to build off of it, [it's public](https://git.wetfence.xyz/RandyTheSilly/pebble-misc/src/branch/main/fonts) and easy to modify!
