David Williams e368f15a7f Add an option (-p) to force use of SB_PLL40_PAD 
When a clock is applied to a dedicated clock pin, SB_PLL40_CORE is no longer the correct primitive to use.

Also the name of the clock input must be PACKAGEPIN (rather than REFERENCECLK)

README 

Project IceStorm aims at documenting the bitstream format of Lattice iCE40
FPGAs and providing simple tools for analyzing and creating bitstream files.
