Version 1.5.1

[1.5.1] - 2026-03-05

Added

• Delete Saved Locations: A "Delete Location" button has been added to LocationWidget (used
  by both the main GUI location popup and the wizard). When a saved location is selected from the
  drop-down, the button becomes active; clicking it shows a confirmation dialog and, on
  confirmation, removes the location from ~/.sew_wizard_config.json and from the drop-down.
  A delete_location() method was added to ConfigManager to support this.

Fixed

• Nikon burst mode not reset after take_burst: After a take_burst command completed, the
  Nikon camera's capture mode (capturemode / stillcapturemode) and burstnumber were left in
  burst/continuous state. All subsequent take_picture commands therefore fired bursts instead of
  single frames. take_burst now resets the camera back to single-frame mode (and burstnumber
  to 1) immediately after the burst capture. As a second layer of defence, take_picture also
  explicitly enforces single-frame mode on Nikon cameras before each capture.
• Timezone detection for sea/ocean locations: Observing locations over water (e.g. in the
  Mediterranean Sea) were assigned Etc/GMT (UTC) because TimezoneFinder.timezone_at() only
  covers land polygons. The new _find_timezone() helper in reference_moments.py now uses
  timezone_at_land() first; when that returns None (sea location), it scans surrounding
  points at increasing step sizes (0.5°–5°) until the nearest land timezone is found. This
  ensures that, for example, a location at 39.924°N, 1.4271°E is correctly assigned
  Europe/Madrid instead of UTC. The same fix is applied to the job-scheduling table in the
  GUI (gui.py).
