Initialize ItemProperties from dict

[PeaceNlove]

Is your feature request related to a problem? Please describe.
With the old deprecated contentmanager add function, it was possible to create a new PortalItem from a dict.
With the latest versions of ArcGIS API for Python we need to do this using a Folder and a ItemProperties object
In this case I cannot use my dict and I need to initialize the ItemProperties object.
There is no option to convert my dict to ItemProperties object and a dict unpack doesn't work

item = {
    "title":"Topo_RD",
     "type":"Vector Tile Service",
    "typeKeywords":["Data","Service","Vector Tile Service"],
    "tags":["topo","rd","vector","tag"],
    "url":"https://tiles.arcgis.com/tiles/nSZVuSZjHpEZZbRo/arcgis/rest/services/Topo_RD/VectorTileServer"
}
item_props = ItemProperties(item)
TypeError: ItemProperties.__init__() missing 1 required positional argument: 'item_type'

item_props = ItemProperties(**item)
TypeError: ItemProperties.__init__() got an unexpected keyword argument 'type'

Describe the solution you'd like
A ItemProperties.from_dict static function would be lovely

itemprops = ItemProperties.from_dict(item_dict)

Describe alternatives you've considered
Right now I just do a folder.add(item_dict) but this isn't officially supported according to the docs and for instance the tags are not set in a proper way
