Making the default bold parameter equal to that given in the docstring

Also, why don't we allow path_effects to be set on a scalebar and its text? This is what I've been doing for my entire career, as often neither white nor black works on an image with a lot of contrast, but black outlined with white or the reverse does so. This is something I support in my Kelvin_STEM scalebars, but if I could just call this it would be even nicer. You'd only need one parameter:
"outline_color": None (default: off)
And then if you supply anything that looks like a color (e.g. named color, hex sequence for a color or a 3- or 4-tuple), then it uses path_effects to draw a Stroke around the text and the bar. I can write the code if you think this is a sesnible plan.

Agreed this would be helpful @maclariz! I'm sure someone will get to it at some point, but feel free to make the change yourself if you want it quickly :) Always happy to approve and merge quick PRs like that.
