[dependabot]

Bumps github.com/oschwald/maxminddb-golang/v2 from 2.0.0-beta.3 to 2.0.0-beta.5.

Release notes

Sourced from github.com/oschwald/maxminddb-golang/v2's releases.

2.0.0-beta.5

• Added Offset() method to Decoder to get the current database offset. This enables custom unmarshalers to implement caching for improved performance when loading databases with duplicate data structures.
• Fixed infinite recursion in pointer-to-pointer data structures, which are invalid per the MaxMind DB specification.

2.0.0-beta-4

• BREAKING CHANGE: Removed experimental deserializer interface and supporting code. Applications using this interface should migrate to the Unmarshaler interface by implementing UnmarshalMaxMindDB(d *Decoder) error instead.
• Open and FromBytes now accept options.
• BREAKING CHANGE: IncludeNetworksWithoutData and IncludeAliasedNetworks now return a NetworksOption rather than being one themselves. These must now be called as functions: Networks(IncludeAliasedNetworks()) instead of Networks(IncludeAliasedNetworks). This was done to improve the documentation organization.
• Added Unmarshaler interface to allow custom decoding implementations for performance-critical applications. Types implementing UnmarshalMaxMindDB(d *Decoder) error will automatically use custom decoding logic instead of reflection, following the same pattern as json.Unmarshaler.
• Added public Decoder type and Kind constants in mmdbdata package for manual decoding. Decoder provides methods like ReadMap(), ReadSlice(), ReadString(), ReadUInt32(), PeekKind(), etc. Kind type includes helper methods String(), IsContainer(), and IsScalar() for type introspection. The main maxminddb package re-exports these types for backward compatibility. NewDecoder() supports an options pattern for future extensibility.
• Enhanced UnmarshalMaxMindDB to work with nested struct fields, slice elements, and map values. The custom unmarshaler is now called recursively for any type that implements the Unmarshaler interface, similar to encoding/json.
• Improved error messages to include byte offset information and, for the reflection-based API, path information for nested structures using JSON Pointer format. For example, errors may now show "at offset 1234, path /city/names/en" or "at offset 1234, path /list/0/name" instead of just the underlying error message.
• PERFORMANCE: Added string interning optimization that reduces allocations while maintaining thread safety. Reduces allocation count from 33 to 10 per operation in downstream libraries. Uses a fixed 512-entry cache with per-entry mutexes for bounded memory usage (~8KB) while minimizing lock contention.

Looks like github.com/oschwald/maxminddb-golang/v2 is up-to-date now, so this is no longer needed.
