v0.2.0

Updating this mostly because I've added a ton of stuff to the sodetlib docker images, including spt3g/so3g and sotodlib installations. So people will need to upgrade to the v0.2.0 docker in order to run any of the new G3 reading functions.

This adds three sodetlib wrappers for the pysmurf streaming functions in the sodetib/smurf_funcs/smurf_ops module:

• stream_g3_on to wrap stream_data_on
• stream_g3_off to wrap stream_data_off
• take_g3_data to wrap take_stream_data

These three functions will also set the pysmurf-action, action timestamp, and a custom tag string that will be sent to the g3 files through the metadata pipeline.
