Update esqlabs plot configuration

https://github.com/esqLABS/esqlabsR/blob/0ab711d648c098647acb1bbd76526732f3a627fd/R/utilities-figures.R#L164

The shapes seem not to be supported by TLF any more. Example:

obsData <- DataSet$new(name = "obsData")
obsData$setValues(1, 1)

myDC <- DataCombined$new()
myDC$addDataSets(obsData)

plotConfig <- esqlabsR::createEsqlabsPlotConfiguration()
plotIndividualTimeProfile(myDC, plotConfig)

In case you can't see it (copying from the plot tab produces weird resolution) - the "symbol" is plotted as a 16.
