Use JSON formatting for report data

[Mandy-cyber]

To-do:

• [x] In map.py create json file of report data after lat/long pairs have been created.
  • First make dataframe of info and use panda's to_json() method
• [x] Change map.js to TypeScript file.
• [x] Make getJson() function that returns an array of objects of the report data
• [x] Make createMarker() function and call .forEach() in initMap() for getJson() return

Future Plan:

• Make cache of json data so we don't have to remake the json file every time a report is made

Works with dummy data but will run it all again when report form is made and integrated with the back-end.
