Feature Request: password-based file encryption using AES

[jnoel-hrs]

My company needs a mechanism to stream data to local file storage, encrypting the data as it comes in (data comes in sporadically from several different sources over time). I took a stab at implementing this here: AESEncryptedFile.swift

The goal is basically to have something similar to the AndroidX EncryptedFile API, which is a turn-key solution for encrypting data via streams.

However, my above implementation is failing in the unit test I wrote because the data seems to be either getting cut off, or is all NULL bytes.

Any help to fix would be greatly appreciated, and if this looks like a good addition I'll happily open a PR for it.

Thanks!

Managed to get this working with a different repo IDZSwiftCommonCrypto - although I suspect the main issue was that I was relying on hasBytesAvailable which apparently is not always reliable.
