`tw.style` should accept falsey values in object syntax

[ferretwithaberet]

Migrated from nativewind + classnames. tw.style is awesome, but, unlike classnames, it does not accept any value when using object syntax, it only accepts boolean.
Is this intentional? Or can this be changed to match the behavior of classnames?

Example

export type ComponentProps = {
  vertical?: boolean;
}

export const Component = (props: ComponentProps) => {
  const { vertical } = props

  return <View style={tw.style({
    'flex-row': !vertical,    
    'flex-col': vertical,
  })}>
    <Text>Test1</Text>
    <Text>Test2</Text>
  </View>
}

it's been a while since i wrote it, but i think the reasoning here is that we (unlike with classnames) also accept RN style objects like { resizeMode: 'repeat' }, which get merged directly into the final style object, so we use the boolean-ness of the value to distinguish that the key is actually another utility name, so we can treat it that way. does that make sense? we have to support stuff like this:

tw.style(`foo bar`, { resizeMode: `repeat` }, {'flex-row': !vertical});
