fix: Allow Integration<T> constructor to have arguments

[sod]

Relax the constructor signature so it may have arguments. Someone might wanna do:

class MyCustomIntegration implements Integration {
    public static id = 'MyCustomIntegration';
    public name = MyCustomIntegration.id;

    constructor(public options: {patterns: RegExp[]}) {
    }

    public setupOnce(addGlobalEventProcessor: (callback: EventProcessor) => void, getCurrentHub: () => Hub): void {
        addGlobalEventProcessor((event: Event) => {
            const self = getCurrentHub().getIntegration(MyCustomIntegration);

            if (self && self.options.patterns.some(rx => rx.test(/* ... */)) {
                return null;
            }

            return event;
        });
    }
}

But getIntegration(MyCustomIntegration) complains, that MyCustomIntegration doesn't match the signature, as arguments in the constructor aren't allowed.
