DeepVision-Web: solder bridges are found better

Solder bridges are still the weakest kind of defect, but the new model finds them much better thanks to real examples. Of 133 defects that had no type yet, 59 were solder bridges, so the second test board now has 52 bridges on the top side instead of 15 and 20 on the bottom instead of 6, and the figures per defect type finally mean something. Private project — only occasional previews.

One step back: missing parts on the bottom side drop from 53 % to 33 %, but with only 15 cases that is not reliable yet. Next: more real bridge examples.
