improve fileHandler support for redistributePar

This is the final part of refactoring for EP1822 with various base functionality already added into develop.

added enhancement label

requested review from @Mattijs

assigned to @andy

changed the description

@Mattijs - should be functionally similar to the previous ep1822 branch. Would be a good basis for further testing (cc: @Chiara).

The first commits ("redistribute clouds" ... "broadcast dyanamicCode") can presumably be added into develop for the 2306 release (as you like). The final commits addressing redistributePar pieces likely still need more shake down.

The field redistributors have adjusted to handle either the legacy bool control (isWriteProc) or with dedicated file-handlers. This should allow smoother transitioning in the mid-term.

@Prashant and @Mattijs - this is the current snapshot state, rebased/reworked on top of develop.

Includes Mattijs' changes for checking for sub-blocks within collated.

Deem it as being ready for some testing.
