Some important TYPES should be exported by the Client

[rjborba]

I've noticed that some TYPES should be exported by the client so whoever is using it, can leverage it without having to redefine them.

Form example:
public async search(query: ClientSearchParams, config?: SearchConfig): Promise<Nullable<Results<AnyDocument>>> ...

Should be:

export type OramaResults = Promise<Nullable<Results<AnyDocument>>>

public async search(query: ClientSearchParams, config?: SearchConfig): OramaResults ...

So people can do:

import { OramaResults } from "@orama/orama"

const anotherFunction = (results: OramaResults) => {
....
}

....

const results = await client.search(...)

anotherFunction(results)

I've mentioned OramaResults type here, but it should be applied by all exposed functions that returns something that is a non-primitives type
