Gowin. Preparing to support the 5A series. 

Family recognition is added, as well as minor fixes, but base generation
itself is not allowed for GW5 - this gives the ability to test the next
Apicula release and still not break installations for those who simply
specify `HIMBAECHEL_GOWIN_DEVICES = "all"`.
