Banana encode an object using L{banana.Banana.sendEncoded}.
@param bananaFactory: A no-argument callable which will return a new,
unconnected protocol instance to use to do the encoding (this should
most likely be a L{banana.Banana} instance).
@param obj: The object to encode.
@type obj: Any type supported by Banana.
@return: A L{bytes} instance giving the encoded form of C{obj}.

Assert that L{banana.Banana.sendEncoded} raises L{banana.BananaError}
if called with the given object.
@param obj: Some object that Banana does not support.
@param name: The name of the type of the object.
@raise: The failure exception is raised if L{Banana.sendEncoded} does
not raise L{banana.BananaError} or if the message associated with the
exception is not formatted to include the type of the unsupported
object.
