Thanks @MartijnUH.

Some extra words for my maintainer mates, @peterdesmet and @PietrH.

This issue/feature request came up during the meeting hold with @MartijnUH and @jimcasaer on Monday, Nov 11, in the framework of my support of their modelling research.

The label "urgent" means that this feature will be implemented as version 0.20.x. We all know that it's better to change things after the release of camtraptor v1.0 which is also something urgent, especially now that camtrapdp v1 has been officially released.

However, this feature is:

• very limited on scope (it doesn't impact the work for the release camtraptor v1)
• important for making progress in multiseason research

Let me know if you need any help or input Damiano.

Thanks @PietrH. I will need your help as reviewer. I am planning to work on this this afternoon and tomorrow. I will also ask @MartijnUH to review as major user.

[PietrH]

I will review all the things! :hamster:

Whiel working on this in #289 I noticed that we could easily add the similar argument camera_col and so to be even more camtrapR compliant. Probably something we do not really need but I think it's better to do it now than having to add it at a later stage.

Convention used in camtrapR implemented: Station__SESS_SessionID__CAM_CameraID

[damianooldoni]

I also check that the words __SESS_ and __CAM_ are not present in station_col, session_col and cam_col. Again, this is to follow the guidelines of camtrapR.
