Set maximum width on speakers

[bnb]

Currently if you run the speakers command, the width of the output is currently ~159 columns:

I had to expand my terminal a few times – otherwise I got output like this 😅

Here's a few places where it seems like the width could be reduced a tiny bit:

• Left padding on each column. Changing to 1 space of padding could save 12 columns.
• Bio could be reduced several rows if padding were removed / the link to Chai on npm-stat were changed to a short link like bitly.
