Read the inputs as defined in inputDesc. Returns an int with a bit set for each input that's active.
Some inputs are connected to capacitors, because we want to be able read the state of the buttons that
were pressed before the ESP started up. After the ESP has started, they hinder us: they'll lengthen the
amount of time a button seems pressed, making a short press look like a long one. To go against that, we
switch the GPIOs connected to those to outputs and manually drain the capacitors when not reading the
inputs.
