dfn: Add TI WSON-8 packages

Generate the 2x2 and 3x3 mm2 wson8 packages for Texas Instruments

Thanks - I will cross-check tomorrow if the numbers are all correct according TI datasheets, and then add the generated packages to the base library. Just some minor comments on the code:

• The create_date argument needs to be passed too, otherwise it will change every time the packages are generated.
• The keywords are not exactly what I wrote in Add cmp & dev for OPA858 and LMH6629 LibrePCB-Libraries/Texas_Instruments.lplib#23 (comment) 🙈 The term "wson8" contains "wson", thus "wson" is not needed as a separate keyword.
• IMO, for readability it would be nice to pass all the arguments by keywords like the existing code.

Would you mind to apply those changes? Otherwise I could take it over.

All done.
But let me say that the current code is not self-coherent respect to the use named argument: the large table from line 112 does not use named arguments. I kept the same standard from there, considering that was the right way. In any case it costed me nothing to change.

Perfect, looks all good to me! I have generated the packages: LibrePCB-Libraries/LibrePCB_Base.lplib#160

I tried to apply the same UUIDs as your original packages from LibrePCB-Libraries/Texas_Instruments.lplib#23 to keep your devices compatible with those new packages, but I figured the DFN generator is not (yet) able to do it (generated footprint pad UUIDs are equal to package pad UUIDs, but in your packages they differ) :-/

So the devices will need to be re-created for the new packages (use "duplicate" feature, assign new package, re-create pinout).

Alternatively we could change the DFN generator to allow assigning separate footprint pad UUIDs so we can keep your devices as-is, but I'm not sure if it is worth the effort.

Or if you never ever used your WSON packages in a project, we could keep their package pad UUIDs anyway, then it should not cause any problem. Only if they are used in a project already, we really must not do this.

If you have any preference, let me know ;)

Thanks

It is fine with the new UUID, I will create a new device.

Great, thank you for your patience 🙏
