Nyall Dawson 018ca7c447 [FEATURE] New expression function "attributes"
Returns a map containing all attributes from a feature, with field
names as map keys. We've got featureful, robust support for working
with maps in expressions now, so this allows rapid conversion
of all feature attributes to a map to use with these handy
functions.
