Excel documents the first argument of MIN as optional and returns 0
when there are no numbers. MIN was registered with a minimum of one
argument, so =MIN() returned #VALUE!. The aggregate already returns 0
for an empty list, so only the registered arity needed to change.
Fixes#138

Local clippy 1.96 flags pre-existing patterns the code has always had:
manual range-contains comparisons, a dead `|| true` filter and a
simplifiable boolean. None change behaviour; they only clear the lints
so `cargo xtask ci` passes on a current toolchain.
