Client release v1.5.0

Python Version Support

• Python 3.8 is now supported in the client.
• As Python 3.5 has reached End Of Life, it is no longer supported by the descarteslabs client.

Tasks Client

• Altered the behavior of Task function creation. Deprecation warnings will be issued when attempting to create
  a Task function for which support will be removed in the near future. It is
  strongly recommended to test any existing code which uses the Tasks client when upgrading to this
  release.
• New tasks public images for for use with Python 3.8 are available.

Workflows (channel v0-17) - Fixed

• .pick_bands supports proxy wf.Str objects; .unpack_bands supports wf.Str and wf.Tuple[wf.Str, ...].
• Better performance constructing a wf.Array from a List of numbers (like wf.Array(ic.sum(["pixels", "bands"])))
• No more error using @wf.publish as a decorator on a function without a docstring
