Override the flush() and read() methods to return the correct Channel…

… subtype (java-native-access#192)

Motivation:

We should override the flush / read method so we return the correct sub-type for method chaining.

Modifications:

Add missing overrides and implementations

Result:

Be able to correctly method chain
