updated flow latency analysis stuff.
We now have an explicit report entry element for sampled latency. It is
currently added by the component when it is sampling. This is separate
from the processing latency.
Will need to add it for the connection if the bus is sampling, i.e.,
operates periodically.
Added capability to generate report for Synchronous and Asynchronous.
Synchronous does the reduced sampling latency by rounding up rather than
adding the full sampling latnecy. It does so by adding the difference
needed to round up.
