Bump com.maxmind.db:maxmind-db from 4.1.0 to 4.2.0

[dependabot]

Bumps com.maxmind.db:maxmind-db from 4.1.0 to 4.2.0.

Release notes

Sourced from com.maxmind.db:maxmind-db's releases.

4.2.0

• Fixed decoding of data pointers with offsets of 2 GiB or greater. Records beyond that boundary could previously fail with IllegalArgumentException.
• Fixed skipping unknown four-byte pointers during typed decoding. Skipped values that extend past the database are now rejected.
• Fixed UTF-8 decoding across buffer chunks. Malformed decoded strings and truncated values now throw InvalidDatabaseException.
• Added decoder limits to prevent excessive CPU and memory use from crafted databases: 65,536 decoded or skipped values, 128 nested containers, and 2 MiB of encoded string and bytes payload per operation. Exceeding a limit throws InvalidDatabaseException. See https://github.com/maxmind/MaxMind-DB-Reader-java/blob/HEAD/UPGRADING.md for accounting, decoded-value validation, and collection capacity-hint changes.
• Improved decoder performance and reduced per-lookup allocation, including UTF-8 string decoding.
