Clean up /opt directory in geospatial

[rdenham]

The rocker/geospatial:4.2.2 image seems to have a fair bit of leftover build files in /opt/grib2,

I don't think these are needed after the build, so perhaps they could be cleaned up. Looks like they are installed via
scripts/install_wgrib2.sh

Perhaps there could be a bit of clean up in that script to remove unnecessary build files.

indeed, good catch. A PR would be welcome!

(it may also be worth deprecating that script entirely, I've found that recent GDAL versions from OSGEO handle grib files just fine already...)

[rdenham]

Thanks @cboettig I'll create a PR and update this issue

[rdenham]

See this PR #576

I tested reading of grib file using gdalinfo, and also terra::rast and seems fine.

There may be others who rely on wgrib but I wasn't sure how to identify those to check if they would be affected.

Reopen as it has not been resolved for focal based images.
