Option to convert automatic detections to annotations

[mzur]

Add a button to convert the locations of automatically detected laser points to annotations. This could make it easier to fix wrong detections and also allows users to export the locations in reports (see discussion https://github.com/orgs/biigle/discussions/618).

Add a note to https://github.com/biigle/community-resources/tree/master/convert-laser-points once this is implemented, as the script will become obsolete with this.

Converted annotations should become ML annotations: biigle/core#679
