Use a slice to back the data instead of adding directly to the channel
for two reasons (this may change in the future though):
* kopia loads all data about a directory at the same time
* consumers of the DataCollection may not pull items from the channel
at a fast rate, which could block adding to the channel. This could
lead to delays in discovering other directories to traverse in
multi-threaded scenarios
