Support for multiple localePrefix modes based on locale

[george-roussos]

Hi!
Is it possible to add functionality for multiple prefix modes?
Eg if we have en-us, en-gb and en-ie and want to adopt a custom prefix for en-ie, but not the other two:

  localePrefix: {
    "en-us": {
      mode: "never",
      prefixes: {},
    },
    "en-gb": {
      mode: "never",
      prefixes: {},
    },
    "en-ie": {
      mode: "always",
      prefixes: {
        "en-ie": "/en",
      },
    },
  },

Would be great for some locale exceptions. This is possible in middleware (if looking at the top level domain e.g.) but for route matching over in usePathname() this would be needed in config.ts.

Thank you! 👍
