A trace exercising multiple-target detection support

I'm including a trace demonstrating this quirk of the hardware functionality,
to support future testing.

As a side note, from some skillful testing using a bunch of MiFare UltraLight
tags, it appears that it can support up to at least *4* targets of the same
type in range:

4 ISO14443A passive target(s) found:
