TODO

- bug: when the session is started by megatools dl, it will have an
  empty fs_nodes list, so next call to megatools ls will return empty
  results and user needs to do --reload

- add usages to the code

- only retry on non-persistent errors
- rework streaming (split download function into a streaming core and a wrapper)

------

- better abort mechanism for http workers
