Field binning fixes to pass fields and setters to configure binning

[ikbuibui]

• Added a type called FieldInfo which is how users are now supposed to pass fields to the binning plugin.
  This was necessary because users cant directly access the field data box from the binning setup. This is because binning setup is called on plugin load, and this happens before the fields are registered with the data connector.
  The FieldInfo object is only passed to the binning functors AFTER being transformed to the corresponding field databox.
  Similarly, for passing field information when doing particle binning, passing a FieldInfo object as extra data will provide the user with access to the field databox.
• Fixed setters of field binning data configuration not working (for example dump period)
• Made the integer linear axis binning more robust against overflows by using 64 bit types internally (thanks @pordyna for testing an axis with almost a million bins)
• Add a domain origin LOCAL_WITH_GUARDS to be used with DomainInfo, mainly with the view of making local field boxes correctly usable more easily. Added an example to the documentation which shows how to use field binning correctly
• Fix getParticlePosition missing a cast, fixes cases where integral cell sizes are used

I am on vacations so an other admin can take over.
