Inconsistency in OTN detection data outputs

[edwardlavender]

Doing a bit more skimming through the source code looking at the different data formats.

Both ato_to_otn.R and imos_to_otn_detections.R output an OTN-style data.frame but with inconsistent naming conventions for the columns.

For example, in ato_to_otn.R, around L79:

det_df$dateCollectedUTC <- ato_det_joined$datetime
det_df$tagName <- ato_det_joined$transmitter

These names differ from those assigned in imos_to_otn_detections.R around L38:

date_and_time = detection_datetime,
tagname = transmitter_id,
