Conan: Update remotes

[Croydon]

Description

Bintray is now down, see e.g. https://blog.conan.io/2021/02/05/JFrog-announces-sunset-bintray.html

The new URL for the Conan Center is https://center.conan.io

For the same reason, the conan-community remote does not exist anymore, but almost all recipes are migrated to the Conan Center by now

Thanks for the update @Croydon. Did you verify if the Conan build process works as expected with this change? If not, we will have to figure out which combination of package versions works via the updated remote repository, and if we need any changes to documentation.

@vmalia Do we still need this PR? If not, can we close it?

Sorry for the late response.

Did you verify if the Conan build process works as expected with this change?

I did not. But the other remotes are non-existant anymore. Migrating to the new one is certainly less broken 🙂

@Croydon I agree, but we cannot merge untested and/or not working changes.
On a separate but related note,
I found that Reference-LAPACK Conan package is no longer maintained and builds fail due to the missing package. Newer Conan version has out-of-the-box support for the Intel DPC++ compiler. I checked 1.42.

Currently, Conan builds are broken due to various factors.

Closing due to #267
