Support geo types

### Is your feature request related to a problem or challenge?

Geo types were added to the Iceberg spec, see [this PR](https://github.com/apache/iceberg/pull/10981).

There is another issue with [Iceberg Rust geo examples](https://github.com/apache/iceberg-rust/issues/1287).

This issue is to implement geo types in Iceberg Rust.

### Describe the solution you'd like

Developers are currently implementing geo types in apache/iceberg, see [this pull request](https://github.com/apache/iceberg/pull/12667). Hopefully similar changes can be made to apache/iceberg-rust.

### Willingness to contribute

None

Start by reading the Iceberg specification changes and the linked apache/iceberg pull request, then compare them with the existing type support in apache/iceberg-rust. Review the related Iceberg Rust geo examples issue to identify expected behavior. Done means implementing the geo types in Iceberg Rust with matching examples or validation.
