Misc `component_threshold` improvements

[Estecka]

• component_threshold does not support transforms. This should be easier to implement now that transforms are no longer limited to strings. Adding a couple of arithmetic transforms might be useful for this module.
• component_threshold does not support item properties. E.g: item_count cannot be used with this module.
• The names of the modelRange parameter options differ from the names of their equivalent transforms. In both cases, is it better for "equal" to be an adjective or a 3rd person verb ?
