Looks up a string by its dynamic atom bits.

(&self, bits: u32)

	/// Looks up a string by its dynamic atom bits.
	fn lookup(&self, bits: u32) -> Option<&'static str> {
		debug_assert!(Self::is_dynamic(bits), "lookup() called on static atom bits");
		let index = (bits & ((1 << ATOM_DYNAMIC_BIT) - 1)) as usize; // Mask off dynamic bit to get index
		self.bits_to_str_vec.read().unwrap().get(index).copied()
	}

	/// Returns true if the given bits represent a dynamic atom.
