PicoGraphics - measure_text measures long

[ahnlak]

When using measure_text, it includes any spacing applied to the final letter. This is a pretty minor problem until you start working at higher values for scale and spacing.

As a crude example, consider a spaced out string of 'Pimoroni': as things currently stand, the function will measure
P i m o r o n i
(with the trailing space), while a more useful measure (for things like centering) would be
P i m o r o n i
(sans trailing space).

I thought I'd raise an issue for a sanity check before I actually starting changing the code :-)

Nope!!!.. you are not insane. I would agree.

Fix in. I'm assuming there's a terribly clever way @Gadgetoid can blend that into the eleventy-million branches 🤣
