siunitx v3 beta 2

Following up on the recent first beta for siunitx, I’ve now made a second beta available. There was only one issue picked up so far by testers, plus of course those I’ve spotted myself. In particular, I’ve allowed a way to set the text font manually if simply resetting back to the standard one doesn’t work. I’ve also sneaked in a late addition: the ability to parse and print uncertainties the way NIST seem to suggest they should appear.

Assuming that I get no major issues coming up, I plan to put this out as the first v3 release in a couple of weeks time: before the next LaTeX kernel update!
