...    features={"cat": ["A", "A", "A", "A", "B"]},
...    indexes=["cat"],
... )
>>> b = a.enumerate()
>>> b
indexes: [('cat', str_)]
features: [('enumerate', int64)]
events:
    cat=b'A' (4 events):
        timestamps: [-1.  2.  3.  5.]
        'enumerate': [0 1 2 3]
    cat=b'B' (1 events):
        timestamps: [0.]
