Indexing issues: syntax error and incompatibility with python 3.9

[ecogest]

Hello,

First, thanks for this program which looks amazing in nvim.

Still, I encountered a few issues with cppman -r:

• The easiest to fix is that indexing is broken by python 3.9 since threading.Thread 's method isAlive() has been renamed to is_alive(). (error message: "error: 'Thread' object has no attribute 'isAlive'") -> file: crawler.py, l.91
• The second issue, with an older version of python (in my case I used python 3.8.6), that I get a error: near "(": syntax error at the end of indexing (I tried both cppreference.com and cplusplus.com). No idea why.
• Hence with the default database (since I can't rebuild the index), I can't find some very basic pages of cppreference like https://en.cppreference.com/w/cpp/string/basic_string/getline (I can only get https://en.cppreference.com/w/cpp/io/basic_istream/getline)

I am on debian 10, I tried installing cppman via pip and brew (never managed to make the indexing work properly, and debian repo's cppman does not support nvim).

Regards.
