Type predicate for easier type checking

[PumpedSardines]

PR to address my complaint in issue #27. Instead of the return type being true or false, the function should return if the value is a object or not.

The point of this function is to return true or false if the value passed in is an object, and it does. I don't understand your issue.

@windusayles Take this following example if "isObject" returns a bool

const myVariable: unknown = ({ foo: "bar" }) as any;

if(isObject(myVariable)) {
   // TypeScript still sees myVariable as unknown in this scope
}

And this is an example if isObject returns val is { [key: string]: unknown }

const myVariable: unknown = ({ foo: "bar" }) as any;

if(isObject(myVariable)) {
   // TypeScript now sees myVariable as { [key: string]: unknown }
}
