Upgrade voltage and current limits for the GPA #41

We found that a 24V supply was inadequate to drive more than ~4.5 amps in the low field scanner gradient coils. We added a second 24V in series. Buffer file is updated, and some capacitors and resistors need to be changed for the new ~50V VCC

Requires new buffer design design (issue linked)

Buffer is done, waiting on components and current-sense wiring

Waiting on capacitors to replace (from finished #44)
