streammap-ext

This is a fork of StreamMap from tokio-stream crate. The only difference between the implementations is that this version of StreamMap next returns Option<K,Option<V>> instead of Option<K,V>. This is to allow the developer to be aware when a stream is being dropped from the StreamMap, without the need to implement a Drop trait which can be troublesome in some cases (e.g. the drop flow requires async code).

After releasing this crate, I'll open a discussion to consider how to contribute it back to the original crate (as a different name, maybe a PhantomData that marks behavior, or maybe change the current behavior to this).
