Database and process tweaks

A lot of work on the database and started to play with the process route. Was able to import `52078` records from version 1 with the following script:

```
INMATES = "http://cookcountyjail.recoveredfactory.net/api/1.0/countyinmate/"

def get_json(url, limit=100, offset=0):

    r = requests.get(url, params={'limit': limit, 'format': 'json', 'offset': offset})
    print(r, r.url)

    return r.json()

if __name__ == '__main__':

    data = get_json(INMATES, 0)
    data = data['objects']


    for row in data:

        phash = row['person_id']

        if phash is not None:

            gender = row['gender']
            race = row['race']

            r = requests.post('http://localhost:5000/process', data={'data': json.dumps({'hash': phash, 'gender': gender, 'race': race}) })

            print(r)
```
