v0.6.0 Expend the event loop and add time duration label

Besides the count of the edge on the label, the duration stats are also calculated to be shown. Add distinct_repeated_events to be able to expand the repeated events to have a better internal understanding. Add ability to use external dot program to render the graph, it will be faster in some cases.

v0.5.0 Faster ⚡️ Faster

This update is mainly about performance improvements. With many of these tuning/refactoring, 0.5.0 is much faster than 0.4.0. It can be thousands times faster for large dataset, such as event log contains several millions records.

Although the create_pmap() is pretty fast, the rendering part is still on V8's Javascript engine, which can be pretty slow for a graph with many nodes and edges. prune_nodes() and prune_edges() can be used to reduce the final graph's complexity.
