Response does not pass all fields provided by LinkedIn oAuth

[satyavh]

As per the LinkedIn docs, the response from the oAuth flow is:

{
  "access_token": "AQXNnd2kXITHELmWblJigbHEuoFdfRhOwGA0QNnumBI8XOVSs0HtOHEU-wvaKrkMLfxxaB1O4poRg2svCWWgwhebQhqrETYlLikJJMgRAvH1ostjXd3DP3BtwzCGeTQ7K9vvAqfQK5iG_eyS-q-y8WNt2SnZKZumGaeUw_zKqtgCQavfEVCddKHcHLaLPGVUvjCH_KW0DJIdUMXd90kWqwuw3UKH27ki5raFDPuMyQXLYxkqq4mYU-IUuZRwq1pcrYp1Vv-ltbA_svUxGt_xeWeSxKkmgivY_DlT3jQylL44q36ybGBSbaFn-UU7zzio4EmOzdmm2tlGwG7dDeivdPDsGbj5ig",

  "refresh_token_expires_in": 525600
}

However, this library only reports back accessToken and refreshToken.
In other words, expires_in and refresh_token_expires_in are missing from the response.
