07f76275 - feat: detect PGP encrypted content in `partition_email` and `partition_msg` (#1205)

feat: detect PGP encrypted content in `partition_email` and `partition_msg` (#1205) ### Summary Closes #1018. Enables `partition_email` and `partition_msg` to detect if an email has PGP encrypted content. Based on the specification in [RFC 2015](https://www.ietf.org/rfc/rfc2015.txt). The test emails are based on the example email in the spec. If PGP detected content is detected, a warning is emitted and an empty set of lists is returned. ### Testing ```python from unstructured.partition_email import partition_email filename = "example-docs/eml/fake-encrypted.eml" partition_email(filename=filename) ``` ```python from unstructured.partition_msg import partition_msg filename = "example-docs/fake-encrypted.msg" partition_msgl(filename=filename) ```
