[sdiy] DIP LM13700 discontinuation

[Roman Sowa]

So they finally did it! I was asking them for such part years ago, as 
probably many others did too.
Too bad it's only available in SOIC though. A 3mm QFN would have been nicer.
I know I can abuse SSI2130 for this, but that's still 32 pin part, while 
all I need is maybe 6 or so. Then it would fit in 2mm VSON...
