***BREAKING CHANGE**: Replaced`IsZero()` methods with`HasData()` methods on all

result structs (including Names). The new methods provide clearer semantics:

`HasData()` returns`true` when GeoIP data is found and`false` when no data is

available. Unlike`IsZero()`,`HasData()` excludes Network and IPAddress fields

from validation, allowing users to access network topology information even when

no GeoIP data is found. The Network and IPAddress fields are now always

populated for all lookups, regardless of whether GeoIP data is available.

***BREAKING CHANGE**: Replaced all anonymous nested structs with named types to

improve struct initialization ergonomics. All result structs (Enterprise, City,

Country) now use named types like`EnterpriseCityRecord`,`CityTraits`,

`CountryRecord`, etc. This makes it much easier to initialize structs in user

code while maintaining the same JSON serialization behavior.

***BREAKING CHANGE**: Changed`Location.Latitude` and`Location.Longitude` from

`float64` to`*float64` to properly distinguish between missing coordinates and

the valid location (0, 0). Missing coordinates are now represented as`nil`

and are omitted from JSON output, while valid zero coordinates are preserved.

This fixes the ambiguity where (0, 0) was incorrectly treated as "no data".

Added`Location.HasCoordinates()` method for safe coordinate access. Reported

by Nick Bruun. GitHub#5.

***BREAKING CHANGE**: Renamed`IsoCode` fields to`ISOCode` in all structs

to follow proper capitalization for the ISO acronym. Closes GitHub issue#4.

***BREAKING CHANGE**: Replaced`map[string]string` Names fields with structured

`Names` type for significant performance improvements. This eliminates map

allocation overhead, reducing memory usage by 34% and allocations by 56%.

***BREAKING CHANGE**: Added JSON tags to all struct fields. JSON tags match

the corresponding`maxminddb` tags where they exist. Custom fields (`IPAddress`

and`Network`) use snake_case (`ip_address` and`network`).

* Added`IsZero()` method to all result structs (City, Country, Enterprise, ASN,

etc.) to easily check whether any data was found for the queried IP address.

Requested by Salim Alami. GitHub[#32](https://github.com/oschwald/geoip2-golang/issues/32).

* Added`Network` and`IPAddress` fields to all result structs. The`Network` field

exposes the network prefix from the MaxMind database lookup, and the`IPAddress` field

contains the IP address used during the lookup. These fields are only populated when

data is found for the IP address. For flat record types (ASN, ConnectionType, Domain,

ISP, AnonymousIP), the fields are named`Network` and`IPAddress`. For complex types

(City, Country, Enterprise), the fields are located at`.Traits.Network` and

`.Traits.IPAddress`.
