feat: Support Approval process events

[lcottercertinia]

Is your feature request related to a problem?

We do not currently get a break down of individual approval process actions under a Workflow:ApprovalProcessActions event.
There is just one huge block of time assigned to Workflow:ApprovalProcessActions

Describe the solution you'd like

It would be great of the parser could handle these events.
The issue we have at the moment is that some of the events do not seem to have end events.
