No prop to choose from where the wave starts like from Top to Bottom OR Left to Right

example:

<WavyLink to="/" color="#000" start="left" end="right"> Home </WavyLink>

Added direction prop, which controls up/down waves. I will be doing left/right soon so happy to keep this issue open. See this [PR] (#6) for up/down functionality
