[3.2.2] - 2023-04-05 fixed: * fixed incorrect `PartialEq` implementation for `StopwatchImpl` * two running stopwatches with different elapsed times compared equal * fixed incorrect `Hash` implementation for `StopwatchImpl` * two running stopwatches with different elapsed times hashed equally * **BREAKING (though warranted for patch):** for `StopwatchImpl<I>` to implement `Hash`, `I` must implement `Hash`
