[On hold] Impossible dates on calendar when creating an event

[clue4]

Problem: When creating a new event and choosing the dates, we are able to select impossible dates on the calendar (ex: selecting a start date, then selecting an end date that is before the start date)
Solution: Add validation to ensure that users cannot select impossible dates once they choose a start date

Specs:

• If a user selects a start date, they should not be able to select an end date before the start date
  • User should be able to select an end date that is the same date as the start date so long as the end time is after the start time
• If a user changes the start date, allowable end dates should be adjusted accordingly
• Make sure selecting a blank space doesn't do anything -- see Kaleb's additional information below

For information on the final bullet point, see documentation (here)[https://github.com/wix/react-native-calendars#agenda]. Essentially there are certain actions that can be performed when the user taps outside the date fields. For example, the calendar could be dismissed. Ideally, we want to make sure that the calendar is only rendered for each month and the only action that can be taken is to select a valid date.

I ran into problems with this plugin, so my recommendation would be to add as much validation as you can within reason. If there are edge cases such as scrolling a full month backward and then the dates becoming valid again, do not spend more than half an hour on a solution because it's extremely low priority.
