Add range_de to Map-like structs

[maurolacy]

Let's extend range deserialization to map-like IndexedMap, SnapshotMap and IndexedSnapshotMap.

#432 follow-up.

This is partially addressed by #498 and #500, but there are still a number of missing impls:

Map requires:

• sub_prefix_range_de, for completeness. (will be dealt with separately)

SnapshotMap requires:

• prefix_de (done in Add prefix_de to SnapshotMap #541)
• sub_prefix_de (done)
• keys_de (done)
• prefix_range_de (done)
• sub_prefix_range_de (will be dealt with separately)

IndexedMap requires:

• prefix_de (done in Add prefix_de to IndexedMap #542 for completeness)
• sub_prefix_de (done for completeness)
• sub_prefix_range_de

IndexedSnapshotMap requires:

• range_de (done in Add range_de to IndexedSnapshotMap #543)
• prefix_de (done)
• prefix_range_de (done)
• sub_prefix_de (done)
• sub_prefix_range_de
• keys_de (done)
