Adds/Fixes toolbelt power tool sprites and updates Proto Nitrate tools (#5431)

## About The Pull Request

I've added sprites and made them show properly when you put power tools
on belt, this includes: Power Drill, Jaws of Life, Science Power Drill,
Hybrid Cutters

As for Proto Nitrate tools
- Reworked icons and added toolbelt sprites
- Added sci tool variants (Proto Nitrate Hybrid Cutters from science
CAN'T pry open doors)
- Added crafting recipes for new tools
- Reduced crafting time to 3s 
- Fixed Proto Nitrate welder missing flame sprite on its icon
## Why It's Good For The Game

Toolbelts finally look properly

Adding sci variants of Proto Nitrate tools means atmos can hand the
hybrid cutters to crew without worrying about the prying

idk why the hell I originally made crafting time for Proto Nitrate tools
20s but it's just annoying, so I'm cutting it down, you're already
spending lot of time to actually make these crystals and long craft time
makes it pain to mass produce for crew
