simple feature req: add block queue length to logs

[viomck]

would be nice to have the block queue size in this log:

[Blue Blocker] blocked [user](@[handle]) due to Twitter Blue verified.

if too inconvenient i can take a whack at it after work

this number is already available in the context menu (the menu that pops up when you click the extension icon in the toolbar). I'm also working on a queue visualizer ui element

oh that's what it is! thank you!!
