* Converts a human-readable time string to milliseconds.

* Supports units: `ms`, `s`, `m`, `h`, `d`. If a number is passed, it is returned as-is.

*
|
|
* @param time - A time string (e.g. `"500ms"`, `"1.5s"`, `"2h"`) or a numeric millisecond value
|

* @returns The time in milliseconds, or `undefined` if `time` is falsy
|
|
* @throws Error if the string format is invalid
|
|
*
|
|
* @example
|
|
* ```ts
|
|
* inMs("2s") // 2000
|
|
* inMs("1.5h") // 5400000
|
|
* inMs(500) // 500
