Abstracts MapStore and MapLane over the underlying map implementation.

[horned-sphere]

It is now possible to change the underlying map used by MapStore and MapLane. This allows:

1. MapLane<K, V, HashMap<K, V, S>> - Specifying a custom hash implementation for hash maps.
2. MapLane<K, V, BTreeMap<K, V>> - Specifying an ordered standard library B-tree map.

This behaviour is enabled by two new traits swimos_agen::map_storage::MapOps and swimos_agen::map_storage::MapOpsWithEntry. Currently these are only implement for the standard library HashMap and BTreeMap types and are not exposed in the public API (so uses can't add support for more map types).

The type of the map is optional and:

MapLane<K, V> == MapLane<K, V, HashMap<K, V>>
