Add useLightningTimeClock hook

[MatthewStanciu]

This PR adds a React Hook called useLightningTimeClock, which generates an efficient Lightning Time clock. It's super easy to use in a React app:

import { useLightningTimeClock } from '@purduehackers/time/react'

export default function MyComponent() {
  const { lightningTimeClock, normalTimeClock, timeColors } = useLightningTimeClock()

  return (
    <p>{lightningTimeClock}</p>
  ) 
}
