Make DTPF lose fuel efficiency over time instead of instantly (GTNewH…

…orizons#2574)

* track idle time in MultiBlockBase

* save idle time in MTE NBT

* decay DTPF fuel efficiency overtime properly

* spotless

* track idle time in DTPF instead of base MTE

* small refactor to simplify logic

* Delete unused resetDiscount method

* Remove unused override

(cherry picked from commit 79d72d3)
