Idiomatic data import and processing with pandas method chaining for all examples

[drbenvincent]

Move to more idiomatic pandas data loading.

An example...

Before

df = cp.load_data("covid")
df["date"] = pd.to_datetime(df["date"])
df = df.set_index("date")

After

df = (
    cp.load_data("covid")
    .assign(date=lambda x: pd.to_datetime(x["date"]))
    .set_index("date")
)
