Bug with the 'sum' aggregation.

[yygrechka]

When I run the code on the doc page:
import numpy as np; np.random.seed(sum(map(ord, 'calmap')))
import pandas as pd
import calmap

all_days = pd.date_range('1/15/2014', periods=700, freq='D')
days = np.random.choice(all_days, 500)
events = pd.Series(np.random.randn(len(days)), index=days)
calmap.yearplot(events, year=2015)
I get the following result:

Only when I change the aggregation to be mean, I get the expected result:

calmap.yearplot(events, year=2015,how=u'mean')

python version: 3.7.1
pandas version: 0.23.4
calmap version: 0.0.7
matplotlib version: 3.0.1

This is fixed with the addition of a dropzero argument with a default True value for calplot in calplot.

Hi, if this problem still exists and you'd like to create a PR to fix it please direct it to https://github.com/MarvinT/calmap/
That is the version that gets published to pypi and has received several updates to fix some existing issues.
