feat: Add a generic FileStream interface

[edgarrmondragon]

Feature scope

Taps (catalog, state, stream maps, tests, etc.)

Description

This would allow tap developers to easily develop support third-party "filesystem" sources by implementing the interface.

The interface would have to support at least:

• Walking down a directory tree to discover files and nested directories
• Read the contents of a file
• Get some file metadata if available (modified time, Content-Type)
• Handle compression

Note

There's probably more requirements, so I'll add them here while I'm working on the implementation.
