Problems loading data with pandas v1.1.0

[ChantalvanSon]

I have been experiencing some problems that seem to be related to pandas version 1.1.0.

The problem occurs after loading any data with crowdtruth.load(). For instance, I tried loading the data in the Multiple Choice Task - Person Type Annotation in Video tutorial notebook:

data, config = crowdtruth.load(
    file = "../data/person-video-multiple-choice.csv",
    config = TestConfig()
)

After that, all rows in the 'units' data are duplicated. As an example:

data["units"]["input.subtitles"].unique()

>> array(["Italian astronaut samantha cristoforetti uploads a strange photograph she's taken"],
      dtype=object)

Fixing the pandas version to 1.0.5 or 0.25.3 in my virtual env solved the issue, so I think there's some changes in pandas 1.1.0 that are causing problems in loading the data.
