osascript 2020.12.3 and python 3.6.9

[mlliarm]

Hello,

Thanks for creating this, it looks like a cool project.

I tried running the example command that you have on your README.md from inside a virtualenv that had a python 3.6.9 (I know it's pretty old) and got the following stacktrace:

Python 3.6.9 (default, Jan 26 2021, 15:33:00) 
[GCC 8.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import osascript as osa
>>> code, out, err = osa.run('display dialog "42"')

    raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: 'osascript': 'osascript'

Version of osascript I'm running

(osx) milia@Newton:~$ pip list |grep osascript
osascript        2020.12.3

Friendly request:

• Can you please let me know if I'm doing something wrong?
• Is your library osascript (version 2020.12.3) backwards compatible with older versions of python3?
• If yes, and you don't need any additional info from me, could you look into this when possible?

Thank you in advance !
