GRASS GIS Addons: status update

Dear all,

We have recently done a clean-up of long time unmaintained addons (to
avoid confusion):

Moved to GRASS-core (most already years ago):

- i.fusion.brovey: replaced by "i.pansharpen"
- r.fill.gaps: ported to core as "r.fill.stats"
- r.geomorphon: same name
- r.grow.shrink: continued as "r.grow.distance" and its Python wrapper "r.grow"
- v.clip: same name
- v.profile: same name

Removal of outdated addons:

- r.in.arc: replaced by "r.in.gdal" / "r.import"
- r.lfp: replaced by "r.accumulate"
- r.los: replaced by "r.viewshed"
- r.modis: renamed to "i.modis"
- r.out.arc: : please use "r.out.gdal"
- r.sentinel: renamed to "i.sentinel"

Best regards,
