Swapped the PIN and TXT layer purposes so that they match the
"usual" use in the SkyWater GDS files.  Note that the SkyWater
standard cells are done in a weird way with the pin geometry on
a PIN purpose but the pin text on a TXT purpose.  The cifinput
style sky130(vendor) will work to read in these schizophrenic
labels.  Magic will not write out this kind of pin label, but
the Calibre deck appears to be able to handle what magic writes
out.
