* Gowin. Add IODELAY.
Input/Output delay (IODELAY) is programmable delay uint in IO block.
This delay line is enabled before/after the IO pad and allows the signal
to be delayed statically or dynamically during 0-127 stages each lasting
from 18 to 30 picoseconds depending on the chip family.

Add sampling part to IO blocks (input only). This edge detector will
allow to dynamically adjust DDR decoding window in the future.

* Extend Himbaechel API with gfx drawing methods
* Add bel drawing in example uarch
* changed API and added tile wire id in db
* extend API so we can distinguish CLK wires
* added bit more wires
* less horrid way of handling gfx ids
* loop wire range
* removed not needed brackets
* bump database version to 5
* Removed not used GfxFlags
* Gowin. FFs placement.
* Allow clusters to be created from FFs and LUTs;
* Immediately create pass-through LUTs from free LUTs adjacent to FF - at the same time ensure alternating use of LUT inputs;
* In case of constant networks, such pass-through LUTs are disconnected from networks altogether;
* Allow FF to be placed directly into SSRAM slides - this is useful when using synchronous reading.

* Gowin. Fix the port check for connectivity.
What happens is that it's not enough to check for a network, we also
need to make sure that the network is functional: has src and sinks.
And the style edits - they get automatically when I make sure to run
clang-format10.
