community-mirrors.ziggy region aware

[meox]

The community mirrors should declare the location and the region.

Instead of:

    {
        .url = "https://zigmirror.meox.dev",
        .username = "meox",
        .email = "glmeocci@gmai.com",
    },

we could extend it to:

    {
        .url = "https://zigmirror.meox.dev",
        .username = "meox",
        .email = "glmeocci@gmai.com",
        .country = "DE",
        .region = "Europe",
    },

Or declare that they are global (ex: CDNs)
