fetch GPS data from OceanLive server and insert it to the local gpsdata table

[alischandy]

This PR adds a new script, gps_fetch.py, to retrieve, process and insert GPS data from the OceanLive server into the local gpsdata table.

Key changes:

• Added dependencies to pyproject.toml: paramiko for ssh connection,schedule for script scheduling, and python-dotenv for loading environment variables.

• Added gps_fetch.py script that:

  • connects to the Oceanlive server via SSH.
  • fetches unprocessed GPS .csv files on the server.
  • downloads them to the edge device.
  • parses the files to extract gps_datetime, latitude, and longitude.
  • inserts the parsed data to the gpsdata table in the local PostgreSQL database.
  • deletes local copies of processed files.
  • uses a log file to track processed gps files and avoid duplication.
  • scheduled to run every 15 minutes and process all unprocessed gps files.
