This allows independently setting Small and Large Oil Rig notifications for Heavy Scientists and Locked Crate unlocks.

I like that change but one thing you have to change is the lang files. we only translate into english and all other languages are updated by crowdin. so you have to remove that from your commits

Just a note to maintainers - it's generally discouraging to contributers when (useful, non-conflicting and CI passing) PRs are left stagnant/ignored for many months, while more recent PRs are being merged: #382, #392, #418, #419..

You might know (or not) that I've been away from the project for a while. I've recently come back to finish what I started last year, migrating everything to TypeScript. While working on that, I've intentionally held off on adding new features since most of it would need to be rewritten for the TS version anyway.

The few PRs I've merged lately have either been quick fixes or widely requested features that line up with Facepunch's recent updates to Rust+.

Once the TypeScript migration is solid, I'll start going through all the issues, bug reports, suggestions, and PRs.
