upgrade plotly_trace_explorer()

[Andrew-Billington]

Hi,

I am getting an error whenever I used the function plotly_trace_explorer() e.g.

processmapR::plotly_trace_explorer(eventdataR::hospital)

Error in match.arg(coverage_labels) :
'arg' must be NULL or a character vector

I have tried it with a couple of different eventlog and always get the same error.

The error is fixed on github, but note that this plotly variant is somewhat experimental, and doesn't display very well. I'll leave this issue for further reference.
