Feat (useArrayUnique): Custom deduplication

[bpolaszek]

Description

Hey there, thanks @Alfred-Skyblue for the #2597 contribution!

Just adding my 2 cents here with an option to provide a specific property to perform array-of-objects deduplication.

I'm not familiar with Typescript (always used standard Javascript), so I did my best, don't hesitate to point out anything that should be improved.

I think it seems more appropriate to use a custom function here #2612

More cumbersome to my eyes 😕

While I can understand the need for a custom function (I can add this to the PR if you want), the ability to use a simple string

useArrayUnique(list, 'name')

removes unneeded complexity and improves readability IMHO.
