refactor(trace): Support gaps in trace data

This change updates the implementation of the trace converter and
SimTrace implementation to support cases where there is a gap between
samples in the trace data.

This change allows users to specify what to do in case samples are
missing in the trace. The available options are specified in
`SimTrace.FillMode`. Currently, we support either carrying the previous
value forward or set the usage to zero.
