Add support for loading (a) harness(es) on a component

[Heines1983]

It would be great of a harness could also be loaded within a specific component instead of the document root. Now I've added myself two methods but it would of course be better if its included in the package. My code at the moment:

export function getHarnessForComponent<HARNESS extends ComponentHarness, COMPONENT extends ContentContainerComponentHarness<string>>(
    query: HarnessQuery<HARNESS>, component: ChainableHarness<COMPONENT>
): ChainableHarness<HARNESS> {
    return new Proxy<ChainableHarness<HARNESS>>({} as any, {
        get: (_, prop) =>
            (addHarnessMethodsToChainer(component.getHarness(query) as ChainableHarness<HARNESS>) as any)[prop],
    });
}

export function getAllHarnessesForComponent<HARNESS extends ComponentHarness, COMPONENT extends ContentContainerComponentHarness<string>>(
    query: HarnessQuery<HARNESS>, component: ChainableHarness<COMPONENT>
): ChainableHarness<HARNESS[]> {

    return new Proxy<ChainableHarness<HARNESS[]>>({} as any, {
        get: (_, prop) => (component.getAllHarnesses(query) as any as ChainableHarness<HARNESS[]> as any)[prop],
    });
}

In this case, can you maybe use the ComponentHarness.locatorFor? I think it searches inside the component.
