Does not work with 3.10

This line causes an error: https://github.com/lensvol/astboom/blob/master/astboom/visualizers/st.py#L1

» astboom ast < out/ex.py

ModuleNotFoundError: No module named 'parser'

Even on 3.9 this import is raising a warning: DeprecationWarning: The parser module is deprecated and will be removed in future versions of Python

Thank you for reporting this! I will try to do something about this shortly.

This works to me on Python 3.10.1:

I guess those imports could be optional?
Say I'm not even using st visualizer :)
