9dd68aa0e2 ice40: Take placed SB_GBs into account when placing PLLs 
Because the PLLs drive global networks, we need to account for
already existing and placed SB_GBs when trying to place/pack them.

Theses can be user instanciated SB_GBs with BEL attribute, or
SB_GB_IOs that got converted during the IO packing.

This patch assumes that:
 - If a PLL is used the output A global network is always used, even
   if there is no connection to the global output pin
 - If a PLL with a singe output is used, then the B output global
   network is still free to be used by whatever.

6cb4e2e83b ice40/pack: During IO packing, remove any unused input connection 
This is mostly for the benefit of PLL placement because the D_IN_x
ports are used for other purposes when PLL is enabled so we need to
make sure nothing is connected there already. (even an unused net is
too much)

638f84a622 README: update windows build instructions for eigen, python 
The recent addition of "eigen3" to nextpnr necessitates the addition of
"eigen" to the list of vcpkg packages to be installed on Windows.

Add the 32- and 64-bit versions of eigen to the command issued to
install various dependencies.

Also document one possible build command, and note about unpacking
python36.zip.
