Scripted version of LQFP-48-1EP_7x7mm (3.6x3.6mm ep size)

This one got forgotten in my original qfp updates.

The original part was named like it has a 3.6x3.6mm exposed pad but it had a 3.7x3.7mm one. (Even thought the datasheet suggests 3.6x3.6 so the new one is more closely fitting the suggestion in this regard.)

The pads have a larger heel fillet and a smaller toe fillet (the later difference is quite small) Comparison screenshot (blue new, red old)
