Should be done for temptable in ThermistorTable.h, too, but this
would mess up an existing users' configuration.
This tries to put emphasis on the fact that you have to read
these values with pgm_read_*() instead of just using the variable.
Unfortunately, gcc compiler neither inserts PROGMEM reading
instructions automatically when reading data stored in flash,
nor does it complain or warn about the missing read instructions.
As such it's very easy to accidently handle data stored in flash
just like normal data. It'll compile and work ... you just read
arbitrary data (often, but not always zeros) instead of what you
intend.
