goem_text - ValueError: The truth value of a DataFrame - python 3.8.3

[nicomy]

Hello,
It seems that geom_text() in plotnine version '0.7.1' is not compatible with python 3.8.3.

In the function __init__ of the class geom_text:

if mapping
raise:
ValueError: The truth value of a DataFrame is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().

This two lines need to be updated :

        if mapping and 'hjust' in mapping:
            mapping['ha'] = mapping.pop('hjust')

        if mapping and 'vjust' in mapping:
            mapping['va'] = mapping.pop('vjust')

Ty for your work, plotnine is awesome :)
