Downtier oreproc GT++ multis to EV and add new EV Mac Stack (#579)

* tier down Multiblock Ore Washer,
add Grisium EV mixer recipe to handle in EV

* Tier down Thermal Centrifuge

* Downgrade Centrifuge to EV
maybe we need to nerf other recipes use Inconel Steel 250 later (Solar Tower, Cryo Stuff)

* Downgrade Bender to EV

* add code for less powerful macerator

it has less parallel than original and must be upgraded (like the distillus) to regain the full parallel bonus

* update tooltip to reflect casing change for T=1

* spotlessApply (#580)

Co-authored-by: GitHub GTNH Actions <>

* fix a bunch of issues with macerators

* Spotless apply for branch Multiblock-EV-change for #579 (#581)

Co-authored-by: GitHub GTNH Actions <>

* add Upgrade T2 Card

* spotlessApply (#582)

Co-authored-by: GitHub GTNH Actions <>

* fix NPE upon placing a fresh maceration controller

* fix

* spotlessApply (#583)
