Itemfilter filter based on a property that is an array of objects

[lubojr]

ItemFilter could filter results based on a property that is an array of objects and I want to match all items where a prop of an object in the array of objects matches the selected value

e.g.

"items": [
  {
    "providers": [
      { "name": "provider1" },
      { "name": "provider2" }
    ]
  }
]

and the filter would filter on unique providers[].name

Here's the file that gets a nested property or a function: https://github.com/EOX-A/EOxElements/blob/main/elements/itemfilter/src/helpers/get-value.js#L8, we'd need to replace that with something that also supports arrays
