merge: Add support for new trace formats

This pull request updates the trace API with the addition of several new trace formats.

- Add support for Materna traces from GWA
- Keep reader state in own class
- Parse last column in Solvinity trace format 
- Add support Azure VM traces
- Add support for WfCommons (WorkflowHub) traces 
- Add API for accessing available table columns
- Add synthetic resource table for Bitbrains format
- Support dynamic resolving of trace formats 

**Breaking API Changes**

- Replace `isSupported` by a list of `TableColumns`
