Remove Oslandia from Service Providers list 😿

[vpicavet]

It is with a certain emotion and nostalgia that a propose to remove Oslandia from the Mapserver service provider's list.

Oslandia has not contributed to Mapserver or affiliated components for years, and it is not on our roadmap neither for the years to come. We do not have any collaborators left in the company having knowledge in Mapserver development.

We have been recently asked for Mapserver services, and I had to redirect to another service providers. As I do not want to mislead people and give them false information, better remove us entirely from the site and keep only true experts.

Keep up the good work, it has been a fun ride !

(ok, I know that doing this PR to remove us is a contribution by itself, with is in contradiction with what I said above, but I think we can definitely consider it an exception, or we have a serious chicken-egg problem ;-)
