Update maxminddb requirement from 0.25.0 to 0.26.0

[dependabot]

Updates the requirements on maxminddb to permit the latest version.

Release notes

Sourced from maxminddb's releases.

0.26.0

• BREAKING CHANGE: The lookup and lookup_prefix methods now return Ok(None) or Ok((None, prefix_len)) respectively when an IP address is valid but not found in the database (or has no associated data record), instead of returning an Err(MaxMindDbError::AddressNotFoundError). Code previously matching on AddressNotFoundError must be updated to handle the Ok(None) / Ok((None, prefix_len)) variants.
• BREAKING CHANGE: The MaxMindDBError enum has been renamed MaxMindDbError and variants have been renamed and refactored. For example, IoError is now Io, InvalidDatabaseError is now InvalidDatabase, DecodingError is now Decoding, InvalidNetworkError is now InvalidNetwork. The MapError variant has been replaced by Mmap (under the mmap feature flag). Code explicitly matching on the old variant names must be updated.
• BREAKING CHANGE: MaxMindDbError no longer implements PartialEq. This is because underlying error types like std::io::Error (now wrapped by the Io and Mmap variants) do not implement PartialEq. Code comparing errors directly using == or assert_eq! must be updated, typically by using matches! or by matching on the error kind and potentially its contents.
• Refactored MaxMindDbError handling using the thiserror crate. Variants like Io, Mmap, and InvalidNetwork now directly wrap the underlying error types (std::io::Error, ipnetwork::IpNetworkError).
• Errors wrapping underlying types (Io, Mmap, InvalidNetwork) now correctly implement std::error::Error::source(), allowing inspection of the original cause.
• The Display implementation for MaxMindDbError has been refined to generally show only the specific error details, often including the message from the source error, rather than prefixing with the variant name.
• lookup_prefix now returns the prefix length of the entry even when the value is not found.
• Fixed an internal bounds checking error when resolving data pointers. The previous logic could cause a panic on a corrupt database.
