yamcs-client 2.0.0

• This release removes the external dependency to the protobuf package. Instead protobuf is embedded into this yamcs-client package. This avoids issues with other installed packages depending on conflicting versions of protobuf. #32

• This release removes old-style imports. Reminder: all classes can be imported from yamcs.client module.

  For example, instead of:

  from yamcs.core.auth import Credentials
  from yamcs.client import YamcsClient
  
  credentials = Credentials(username="admin", password="admin")
  client = YamcsClient("http://localhost:8090", credentials=credentials)

  do instead:

  from yamcs.client import Credentials, YamcsClient
  
  credentials = Credentials(username="admin", password="admin")
  client = YamcsClient("http://localhost:8090", credentials=credentials)

• TimelineClient: Add delete_items operation to batch-delete items. This is a lot faster than deleting items one-by-one.

• TimelineClient: Default for the ItemBand setting space_between_items was changed from 0 to 7. And space_between_lines was changed from 2 to 7. This allows for a bit more whitespace between items, which gives the Yamcs Web UI some space to draw connections between depending activities.

• TimelineClient: The code was adjusted to API changes in Yamcs 5.13.0. Backwards compatibility with older Yamcs versions is untested (and unlikely to succeed).

• TimelineClient: The code to add/update items to the Yamcs Timeline was changed. A best-effort was made to keep old code functional, however that will emit deprecation warnings.

  In summary, instead of:

  item = Item()
  item.name = "Test"
  item.start = now
  item.duration = timedelta(seconds=3600)
  item.tags = ["abc"]
  timeline.save_item(item)

  do instead:

  item = TimelineEvent(
      name="Test",
      start=now,
      duration=timedelta(seconds=3600),
      tags=["abc"],
  )
  timeline.save_item(item)

  New classes are available for three different kinds of items: TimelineEvent, TimelineTask and TimelineActivity. See the online documentation for more on this topic.
