Combine arrays of object#25

Thanks for creating this library, there are several libraries that do deep merge, but this is the only one I've seen written in TypeScript. I would like to see a default function for deep merging arrays of objects, such as [the one introduced](https://www.npmjs.com/package/deepmerge#arraymerge-example-combine-arrays) in the deepmerge library. This means that I want to use the following strategy for merging: ```js const x = { a: [{ foo: 42 }] } const y = { a: [{ bar: 42 }] } const expect = { a: [{ foo: 42, bar: 42 }] } ``` Or please provide a sample that uses mergeAndCompare to achieve the same process. Thanks!
