Update eventlet to fix bug in python 3.10

[samlachance]

Hello,

When I attempted to install aprsd in arch linux using python 3.10 I received this error at runtime:

Traceback (most recent call last):

After a bit of searching, I discovered this issue on eventlet: https://github.com/eventlet/eventlet/issues/733

It appears that they've patched the bug but since we're receiving the error I'm assuming we're on the broken version.

Would it be possible to attempt an upgrade to a patched version? I think it is breaking python 3.10 support outright.

Apologies for not making a PR myself -- I'm not familiar enough with python dependency management or this project to do it safely in a reasonable amount of time.

Thanks for the excellent project and 73! Sam, N3SAM

Can confirm that I'm also having this issue on Python 3.10.6
