Add scripts directory with an ADS-B file stats script.

[elliott-ruebush]

Overview

This is a simple Python script to give us some details on ADS-B files so we know roughly what data sizes look like and what kind of SD cards we might need to include in ADS-B loggers. It supports an arbitrary root dir and file extension.

If worth it, we could extend to do this more generally, but it's easy enough to update in the future.

Part of the point of this PR is just to establish a home for our random scripts in a GitHub repo
