Add SMS integration into the app

[MaximilianMeiler]

We're looking to add SMS integration if a user misses their alarm:

https://docs.expo.dev/versions/latest/sdk/sms/
This link should provide some info on how to incorporate texting for both IOS and Android.
Note that we will also need some way to provide a number to text (perhaps the user can enter it somewhere, or even select a contact)
