Coding standards updates

(repeating this Slack conversation here for context)
The initial branch brought the the batchScriptInterface into batchOperations, however that interface should only be applied to the actual Batch scripts. They are the ones that have to implement the interface. BatchOperations is more like an abstract class (probably ought to be). The BatchIperations class should only have to implement the parts of the interface that are optional, not all the non-optional ones. If we make it use the interface then the Custom BatchOperations don't have anything that they MUST implement.... which would cause a bunch of problems for people who need the interface to guide them on what MUST be provided in the script.

I just merged in a fix that will allow you to add something like

public function canBatchRun(): bool {
    return TRUE;
  }

to your BatchOperation and have it determine if it meets your conditions for processing the Batch when cron tries to run it.

Released as 1.0.11 https://www.drupal.org/project/codit_batch_operations/releases/1.0.11 →

Thank you @capysara for working this through with me.
