Bump github.com/oschwald/maxminddb-golang/v2 from 2.3.0 to 2.4.0

[dependabot]

Bumps github.com/oschwald/maxminddb-golang/v2 from 2.3.0 to 2.4.0.

Release notes

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

2.4.0

• Reduced reflection decoding time and memory allocations. A city-lookup benchmark decoding a geoip2-style result allocates 20% fewer bytes (saving 48 B/op) and 2 fewer heap allocations per lookup when utilizing pointer-heavy destination structures.
• Optimized map key decoding by adding a fast path for pointer keys, improving general lookup throughput by 2.7% to 6.4%.
• Optimized tree traversal for IPv6 lookups, resulting in an ~8.8% speedup.
• Fixed pointer-to-pointer chains in malformed database data so decoder entry points reject them consistently instead of following invalid chains.
• Reduced memory mapping overhead and system allocations when invoking OpenBytes and NetworksWithin.
• Cleaned up, simplified, and deduplicated internal decoder and reader structures, removing deprecated type assertion workarounds and unused helper functions.
