generate_watersurfaces_hab: update to v2020

[cecileherr]

Main changes:

• add a control of the file hashes for the input maps (habitatmap_stdized and watersurfaces) based on n2khab::checksum (be sure to use version 2020 and watersurfaces v1.1)
• replace sessioninfo by renv
• add a timestamp (OGR_CURRENT_DATE) to create a geoPackage with reproducible file hash
• add basic checks for the new version of the GeoPackage watersurfaces_hab
• explore errors in geometry and correct them

Here is the rendered notebook:
generating_watersurfaces_hab_rendered_nb.zip

And the new version of watersurfaces_hab:
watersurfaces_hab_2020_gpkg.zip

Excellent work @cecileherr 🎉! You pay attention to various relevant aspects, which is much appreciated.

Interesting to see how you fixed geometries. It seems worth doing that for other habitatmap-derived data sources (see specific comment).

It seems best to update the document title to 'Generating watersurfaces_hab', for consistency with other ones.

I believe the specific comments are just aesthetic or informative and will not affect the actual result (if re-run, the checksum should still be the same).

I checked the xxhsums of the input files, they're fine.

Thanks for attaching the html and data source file (file to be overwritten on the Q-drive as well, where we just save the latest versions).

Indeed, I re-ran the script and the checksum stay the same.

@florisvdh: shall I put the file on the Q-drive or do you prefer to do it yourself?

[cecileherr]

I updated the script to implement your suggestions.

Here is the new version of the rendered notebook (quite big due to the maps):

You're welcome to do so @cecileherr - thanks.

I'll have a look at your update tomorrow.

Nice work @cecileherr, thanks. The maps are an attractive approach to explore differences.

You can leave this PR open, just like PR #50, until dependent work in n2khab is finished. So you can add further stuff here as needed.
