[MIRROR] ChemMaster 3000 printing speed based on servo tier (#2179)

* ChemMaster 3000 printing speed based on servo tier (#82836)

## About The Pull Request

Reverts the maximum number of containers (pills/patches/etc.) the
ChemMaster 3000 can print back to 50. (Recently changed to 12.5 per tier
in tgstation/tgstation#82002) Instead, the servo
tier determines the speed the batch is printed at.

## Why It's Good For The Game

Refilling the buffer and pressing print for every 13 pills is pointless
busywork when there is already a delay now implemented per pill printed.

## Changelog

:cl: LT3
balance: ChemMaster can again print a maximum of 50 pills/patches per
run
balance: Higher tier servos increase ChemMaster printing speed
/:cl:

* ChemMaster 3000 printing speed based on servo tier
