Remove deprecated is_anonymous_proxy and is_satellite_provider fields

These fields have been removed from MaxMind databases. Users should use
the dedicated Anonymous IP database for anonymity detection.

This matches the Go v2 library which also removed these fields.

   - New: `city.subdivisions.iter()` (empty Vec if not present)
   - Leaf values (strings, numbers, bools) remain `Option<T>` to preserve
     the distinction between "not present" and "present but empty"
+- **BREAKING CHANGE:** Removed `is_anonymous_proxy` and `is_satellite_provider`
+  fields from `country::Traits` and `enterprise::Traits`. These fields are no
+  longer present in MaxMind databases. Use the Anonymous IP database for
+  anonymity detection.
 - Error messages now include byte offsets when available, making it easier to
   debug malformed databases. The `#[non_exhaustive]` attribute is added to
   `MaxMindDbError` to allow future additions without breaking changes.
