[tilem] Download ROM over https

[Eeems]

I would recommend tweaking the tilem port to download the rom over https.

IIRC I tried this when implementing but ran into issues when using the system wget.

But worst case we try https and use http as a fallback.

The system wget doesn't fully implement SSL, But the one supplied by toltec does.

https://github.com/toltec-dev/bootstrap is also an option if you want to have a version that works without having toltec installed.
