/**
 * Maps the values emitted by a signal to a renderable function and returns a new renderable function.
 *
 * While it is tempting to use MapSignal for its simplicity, it is important to remember that the
 * renderable function returned by MapSignal will be re-rendered every time the signal emits a new value.
 *
 * In other contexts link `Ensure` or `OneOf`, the renderable function is only re-rendered when the signal
 * changes to a state that requires a different renderable function.
 *
 * @typeParam T - The type of values emitted by the signal.
 * @param vlaue - The signal or value to map.
 * @param fn - The function to map the signal values to a renderable/TNode.
 * @returns - A new renderable function that represents the mapped signal.
 * @public
