Issue Description

The current implementation of the convertTime function requires the duration and source unit of time to be specified in a single object. However, it would be beneficial to enhance the function to accept an input object that separates the duration into individual properties for different time units. For example, { minutes: 5, seconds: 40 } instead of { duration: 340, unit: 'sec' }.

This change would provide a more flexible and intuitive API for users, allowing them to directly specify the duration using a combination of different time units. Additionally, it would eliminate the need for users to calculate the duration manually when dealing with complex time conversions.

Proposed Solution

Modify the convertTime function to accept an input object that separates the duration into individual properties for different time units. The updated function signature could look as follows:

convertTime(input: { minutes?: number, seconds?: number, hours?: number, ... }, output?: UnitOfTime): number;

In this updated signature, the input object can contain properties for different time units such as minutes, seconds, hours, and so on. The function will convert the specified duration into milliseconds by summing up the individual time units and return the result.

Example Usage

import { convertTime } from 'time-morph';

const durationInMilliseconds = convertTime({ minutes: 5, seconds: 40 }); // 340000
const durationInSeconds = convertTime({ hours: 2, minutes: 30, seconds: 15 }, 'seconds'); // 9015
