Add padding to strength bars

[lazyprop]

Pad strength bars with spaces to the left.

This throws a TypeError when wifi_chars is unset.

After looking at this some more, I don't understand why we need to do this when you can just add spaces to the format string?

is there a way to add padding spaces dynamically depending on the length of the string, using format strings? i did this because in dmenu vertical mode, the indentation at which each Wi-Fi name starts varies based on the signal strength, which in my opinion looks bad.

i would understand if you think this is unnecessary and close the PR. on the other hand, if you think it would be useful to have proper tabular formatting in the output, perhaps enabled by an option, let me know. i intend to modify my own installation to do the same, and would be happy to push changes upstream.

Apologies, I'll add some typechecking in case you want to go ahead with this PR.

Would you be able to attach screenshots of what you're describing (before and after the patch)? I'm having a hard time visualizing what you describe, sorry!

After and before adding padding. Note how the networks with different signal strengths have their names misaligned.
