Is your feature request related to a problem? Please describe.

The current implementation of ptracetest compares tests but doesn't allow to ignore span IDs of spans.

Describe the solution you'd like

I would like to remove all notion of equality by span ID.

Describe alternatives you've considered

Right now I change span IDs to the following:

func ignoreSpanID(traces ptrace.Traces) {
	for i := 0; i < traces.ResourceSpans().Len(); i++ {
		rs := traces.ResourceSpans().At(i)
		for j := 0; j < rs.ScopeSpans().Len(); j++ {
			ss := rs.ScopeSpans().At(j)
			for k := 0; k < ss.Spans().Len(); k++ {
				span := ss.Spans().At(k)
				span.SetSpanID(pcommon.NewSpanIDEmpty())
			}
		}
	}
}

I apply this change to the expected and actual sets.
