add RevokeToken via access_token method.

[dlipford360]

hey! I needed a revokeToken method and forked your repo and made one. I tested it and it works. maybe unique_id could be renamed to access_token. it just happened that way when I made it.
On my implementation it's use kinda goes like

• step 1 -> authorization_code passed to BE.
  step 2- > below

//this code is ran. gets accessToken, then uses it to revoke
const access_token = await this.appleAuth.accessToken(authorization_code) 
const revoked_token = await this.appleAuth.revokeToken(
        access_token.access_token,
      )

Thank you for your PR, I really wanted this feature! @ananay could you please merge this?

Sorry I missed this! Thanks for the ping. I can go ahead and test this and merge this.

It's high time that this repo also gets a CI/CD pipeline to make it easy to test stuff out.
