Behaviour on bbox queries for providers that do not support them

[doublebyte1]

This issue is just to flag the fact that bbox queries issued against providers that do not support them, simply ignore the bbox parameter.

For example, in the case of the GeoJSON provider:

pygeoapi/pygeoapi/provider/geojson.py

Lines 156 to 158 in 451f1f0

	# TODO filter by bbox without resorting to third-party libs
	data = self._load(skip_geometry=skip_geometry, properties=properties,
	select_properties=select_properties)

Would it be more appropriated to throw a warning to the user, stating that the bbox filter is not implemented?

I am not sure if there is a rule on how to deal with this, or if this change would be consistent with the pygeoapi behaviour in other occasions, but I would love to hear more thoughts about this.
