QR codes allow 4 different levels of error correction. By increasing the level, larger numbers of data bytes can be corrupted without invalidating the code
In Python3, all division operators promote integers to floats. We need
to downcast back to integer for the polygon vertices.
There was also an unhandled overflow in the QR generation that allowed
more than 512 bits to be loaded. This overflows the type of QR we
generate, so this truncates the input string to 62 bytes ( leaving 12
bits for the checksum )

This updates some of the footprint wizard values to use the default KLC
values for silkscreen, fab, courtyard and text.
Also updates the default QFN settings to create a valid footprint
The text height and thickness settings were never implemented so they
didn't get updated when the options were changed. Added the missing
code to update both parameters.
Added text width parameter so text height and width do not need to be
the same value. Currently both the value and reference fields are set
to the same height and width. Please feel free to change this if you
feel the need to have separate text settings for both the value and
reference fields.
