Add time measurements to plpLog

[egillax]

I think it would be good to add time measurement to each step in runPlp and the total time. I already did so in the arrow branch when I was comparing the old and new performance. See example here in createStudyPopulation .

This requires putting the following as he first thing the function executes:

  startTime <- Sys.time()

And at the end of the function as the last thing it executes:

delta <- Sys.time() - startTime
ParallelLogger::logInfo("Creating study population took ", signif(delta, 3), " ", attr(delta, "units"))

Replacing the text in logInfo with what is appropriate for the function.

Functions which I believe would be useful to add timings to:

• createStudyPopulation
• splitData
• sampleData
• featureEngineer
• preprocessData (there might be one already in tidyCovariates, in that case it can be skipped here)
• fitPlp
• predictPlp
• evaluatePlp
• covariateSummary
• runPlp
