Feature: Overpass Scheduling

[Umang-Rajkarnikar]

Changes made:

Added methods to:

• execute scheduled command sequences
• reschedule leftover commands to next overpasses
• add schedules for the next 7 days
• schedule jobs for satellite on boot (edge case if the server restarts and all jobs are lost)

Created event emitters:

• Once a satellite is added -> Event to add schedules for next 7 days
• Once a schedule has passed -> Event to schedule job for a satellite's next overpass

Added tests:

• For the methods described above in schedule.test.ts

Migrated some files in route/satellite.ts to util folder so now they can be accessed in other areas of the code
