Invalid attribute in PCA9555 config section

[jueank]

The ConfigTemplate file 'PinscapePico KL25Z Adapter - 74HC165 vsn.json' contains initialOut in the pca9555 section. This is marked as an error when trying to save to the Pico. Not usre if this is really an issue. I'm using the current configTemplate with the GUIConfigTool from v0.12 release.

Looks like it's missing from the doc/schema file. I'll add it. (You can just ignore the error message from the editor in the meantime - the software will parse it correctly, or hopefully will anyway!)
