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.

Comece pela documentação de criptografia do Apache Iceberg e compare seu modelo com a interoperabilidade com Spark descrita aqui; em seguida, revise as referências vinculadas sobre criptografia de catálogos Hive e REST. O trabalho estará concluído quando o PyIceberg puder ler e gravar tabelas seguindo o modelo de criptografia e abordar a dimensão do suporte a catálogos.
