Update volunteer availability to be any chunk of time. #158
Description
Context
The way we keep track of availability is using a bitString where 0 is available and 1 is busy.
Issue
Currently volunteer availability only covers from 6am to 9pm every day. (See src/constants.ts)
We should just do 30 minute chunks for every individual time in the week.
Notes
- This issue will require a migration on the backend, and minor code changes. It does not cover frontend code changes.
- Make sure like previously the length of the bitString is validated before being inserted in the DB
