Update to maxmind-db 4.0.0 and use non-deprecated accessors

- Bump maxmind-db dependency from 3.2.0 to 4.0.0
- Update method calls to use record-style accessors instead of deprecated
  JavaBean-style getters in DatabaseReader.java and test files
- Changes include: getDatabaseType() → databaseType(), getData() → data(),
  getNetwork() → network(), getNetworkAddress() → networkAddress(),
  getPrefixLength() → prefixLength()
