UnboundLocalError: cannot access local variable 'global_opts' where it is not associated with a value

[bruiiser]

Describe the bug Unless there is a '~/.i2csshrc' file i2cssh fails with the error message in the title of this report

My config

1. I don't normally have a .i2csshrc file. but adding one that is basically empty addresses the error. I put this content into a config file and got the script to work again:

---
version: 2

3. any and all commands fail in the absence of a config file

Expected behavior Well of course i would expect this NOT to throw the error
