Feature Request: Encryption

### Feature Request / Improvement

Apache Iceberg supports table encryption (https://iceberg.apache.org/docs/nightly/encryption/), and engines like Spark are capable now of writing and reading tables that adhere to Iceberg's encryption model.

This feature tracks PyIceberg supporting this. The eventual goal here would be (1) PyIceberg being able to read tables written by other engines according to Iceberg's encryption model, and (2) PyIceberg being able to write tables according to the encryption model, to be read by other engines. There's also the dimension of catalog support - on the Java side, Hive encryption is implemented and [REST encryption](https://github.com/apache/iceberg/pull/13225) will hopefully be soon.

Comienza con la documentación sobre cifrado de Apache Iceberg y compara su modelo con la interoperabilidad con Spark descrita aquí; después, revisa las referencias enlazadas sobre el cifrado de catálogos Hive y REST. Se considerará terminado cuando PyIceberg pueda leer y escribir tablas siguiendo el modelo de cifrado y abordar la dimensión de compatibilidad con catálogos.
