Fix plot exception: 'seaborn-whitegrid' is not a valid package style, path of style file
when you use adtk==0.6.2 and plot the data, you will get following, that's because the matplotlib which is required by adtk installed don't have seaborn-whitegrid in recent versions. for styles available, you can refer: https://matplotlib.org/stable/gallery/style_sheets/style_sheets_reference.html
from adtk.visualization import plot
from matplotlib import style
plot(s_train) # s_train is loaded before.

To use recent matplotlib versions, we need modify the logic in _visualization.plot, make it compatible with recent versions of matplotlib.
