isHex, isAlphanumeric: prong reorder

On x86 interestingly I can see a reduction in codesize by 1 instruction with this.
While not necessarily faster, it might still reduce codesize a bit and this ordering is also more logical
because it follows ASCII table order. Rust's std uses this ordering too.
See https://zig.godbolt.org/z/PqodY8YqY for the difference.
