cancelled should StartLiveData raise an exception

side effects.

(cherry picked from commit 2ac289c3)

- documentation modified (description, usage exmple)
- clang
- performance test ConjoinXRunsTest (<6 sec with dx, without dx it would be 0.1 sec faster)
- fix ConjoinXRuns (bracket did not close correcly)
- add unit test without dx values in ConjoinXRuns (all other tests run with dx)

- Two unit tests are failing for me: ConjoinXRunsTest and MergeRunsTest (different values event workspace??)

Upper case causes it not to work

re #22143

Refs #22217

- algorithm tooltips for E and Dx
- be more clear about E and Dx values: both are optional inputs but E values are always present in the output workspace and Dx not
- usage example update to show the difference of required and optional inputs, minimum and more inputs

This is to avoid confusion with entropy S.
'j' was originally suggested for this, but this could
be confused for iteration.

The plotting is now done using '.. plot::' directive. Should always stay
up-to-date.
