v0.7.0

• BREAKING: This PR reverts the API change made to the verify method in v0.6.0:

  -async verify(token: string): Promise<{ email: string; state?: string }> {
  +async verify(token: string): Promise<string> {

  v0.6.0 mistakenly assumed state was part of the token, but it is simply returned in a query parameter state to the callback / redirect URI. As such, your application can extract it directly from the request.
