Allow more execution logs output formats in runner

[m-fila]

The runner script #27 was added #29 but it allows only the :graphviz_simple dot graph output for logs.

What is missing:

• gantt plots,
• txt output,
• chrome-trace (once Dagger 0.18.13 or 0.19) is released

The main problem the visuallizations seem work with different logs (to be verified once again)

	LocalEventLog	MultiEventLog
:graphivz_simple	✔️ (with ext piracy)	❌
:graphviz	❌	✔️ (lacking in Dagger 0.18.11-12, but fixed in master)
:plots_gantt	❌	✔️
:plots_gantt_ps	❌	❌
txt	✔️	✔️ (can be formatted to json)	not-compatible between each other
:chrome-trace	❌	✔️
