Add support for ppO2 samples.

Browse Source 
When the PPO2 sample was introduced, we didn't take into account the
fact that rebreathers usually support multiple O2 sensors. The HW OSTC
supports for example three sensors. In order to support multiple values,
without having to introduce a new data structure with an additional
sensor id field, we simply relax the assumption of allowing only one
DC_SAMPLE_PPO2 value per sample. Applications that are not prepared for
multiple values, will automatically use only one of them (probably the
last one).
