readability-identifier-naming NamespaceAliasCase feature request

[Fiero99]

Feature request:

check identifier naming on alias namespaces

Example:

namespace NamespaceAlias = some_namespace; // Warning NamespaceAlias should be namespace_alias

What I already tried:

With .clang-tidy

  - key:             readability-identifier-naming.NamespaceCase 
    value:           lower_case

The following alias namespace is not checked.

namespace some_namespace {}
namespace NamespaceAlias = some_namespace;

I would expect the alias namespace to be in the same format as other namespaces. (Or to be able to configure it using something like NamespaceAliasCase.
