Vincent Ambo aedde913d1 refactor(readTree): Pass all readTree parameters as function args
Instead of having a mix of depot-passed args (for the filter) and args
to the readTree function itself, make everything a single attribute
set of arguments passed to the function.

This also makes it a bit easier to extend this in the future.
