Thanks for the contribution, it will be good to have a more optimised release build. I think it would be better to use lto = "thin" here, what do you think? ThinLTO achieves optimisation results very close to "fat" LTO but with substantially less build time penalty

Actually, I see in the linked issue that all three were compared and fat LTO is doing better at reducing binary size. I'll merge this as-is for now and if build times become an issue we can revisit. Thanks again!
