transform of url from id's to custom object.

[tfjordside]

Problem: we would like to have nicer url's in searches so they don't get like this: https://dev-10072li-fe.testserver.nu/da/nyheder/?categories=35847cb4-6a09-45d3-841d-733d9ad2cfc6

We want to create a mapping handling so we can send an obejct to the useLimboSearch where we can set that

{
   categories: {
       vejle: '35847cb4-6a09-45d3-841d-733d9ad2cfc6'
   }
}

So a search that returns /search?categories=35847cb4-6a09-45d3-841d-733d9ad2cfc6 can return a search /search?categories=vejle

We need to be able to make a custom config for search urls.

Search config already have a urlMapping prop. https://github.com/limbo-works/Limbo.Nuxt.Search/blob/main/composables/useLimboSearch.js#L73

first attempts at implementing is here: https://github.com/limbo-works/Limbo.Nuxt.Search/blob/main/composables/useLimboSearch.js#L624 - it is not working but I think it is the right place to put it.

Currently solution is only needed in the useLimboSearch composable.
