Shipping day!

Spent the last couple of days on everything around the code, which turned out to be way more work than I expected. Setting up git properly, fixing merge conflicts, getting PyPI to accept the upload, writing a .gitignore, creating a release tag. None of this is hard individually but it’s a lot of steps and each one has its own way of going wrong.
Also fixed two real bugs I hadn’t noticed: the tool would crash on non-ASCII characters like emoji, and nothing stopped you from saving the output as a .jpg (which would silently destroy the hidden data since JPEG is lossy). Both are one-liners to fix but they matter.
The project is now on PyPI at pip install steganohide, fully open source, with a proper README and release. It actually works and anyone can try it.
