FreePDK45 first attempt to get LibreSOCIO vbe and ap files to complete FreePDK45-c4m PnR
it is a very bad hack-and-run first attempt, saying "ERROR, can't create segment, NULL layer" because i don't know the layer names (or what to change from what to what) when copying the .ap files from niolib.
at least however it runs... up until "error, tie_x0.ap missing". copy that from nsxlib, i get a new error, "error, buffer_x8.ap missing". so it looks like the entire "ap" set is missing from FreePDK45 cell libraries, not just LibreSOCIO and LibreSOCMem, all .ap files are not there.
i will copy over the set from nsxlib, and report back
