Enhancement in graphics.py to change odds text size

[Maximiliano Mollura]

Please consider to change the followings in graphics.py in order to improve text resizing in forest plot:
-line 127:
def plot(self, figsize=(3, 3), t_adjuster=0.01, decimal=3, size=3, max_value=None, min_value=None):
with
def plot(self, figsize=(3, 3), t_adjuster=0.01, decimal=3, size=3, max_value=None, min_value=None, odds_text_size=12):

-line 216:
tb.set_fontsize(12)
with
tb.set_fontsize(odds_text_size)
