Unit Tests

I was attempting to get this library working with the following code:

import os

import pandas as pd
import quantstats as qs

df = pd.DataFrame(data={
    "afl": [0.0, -0.5, 0.5, 0.2, -0.2],
    "nfl": [0.0, 0.5, -0.5, -0.2, -0.2],
}, index=[
    datetime.datetime(year=2020, month=1, day=1),
    datetime.datetime(year=2020, month=1, day=2),
    datetime.datetime(year=2020, month=1, day=3),
    datetime.datetime(year=2020, month=1, day=4),
    datetime.datetime(year=2020, month=1, day=5),
])
df.index = df.index.tz_localize("UTC")
df.index = pd.to_datetime(df.index)

qs.extend_pandas()
qs.reports.html(df, "SPY", output=os.path.join(self._name, "test.html"))

However I receive the issue TypeError: Invalid comparison between dtype=datetime64[ns] and Timestamp with the following traceback:

venv/lib/python3.11/site-packages/quantstats/reports.py:108: in html
    returns, benchmark = _match_dates(returns, benchmark)

    loc = max(returns[returns.columns[0]].ne(0).idxmax(), benchmark.ne(0).idxmax())

    return invalid_comparison(self, other, op)

The more I tried to solve this the more indexing issues I ran into, I was wondering if the maintainers would object to me adding some pytest tests to try and wrangle this bug?
