Ignore excess samples with the same timestamp.
Ignore excess samples with the same timestamp.

With a time based sample interval, the maximum number of samples for a
single timestamp should be constant. However in practice some devices
occasionally store one or more additional samples with the same
timestamp.

Ignoring those excess samples, allows the parser to proceed, while still
preserving the strict time based interval for the application.
