qol_research adds a configurable research tree of QoL character bonuses, applied as proper technology effects (so they survive reset_technology_effects and play nicely with other mods).

Bonuses:
- In-hand crafting speed
- Inventory size
- Player mining speed
- Movement (running) speed
- Player reach (build / item-drop / resource-reach / reach distance)

Features:
- Every bonus is a real technology with science-pack costs, levels and (where configured) infinite research tiers.
- Startup setting to enable/disable each category.
- Runtime settings for a flat bonus and a global multiplier per category.
- Fully custom tech trees via a custom configuration string.
- Built-in compatibility configs for Space Exploration and Krastorio 2.
