Updated Examples

[RMagician]

Describe the bug
Hey, first of all thanks for the api wrapper. I'm trying to use it for v3 Reports, but not being able to. If you could provide some updated examples would be great. The example in the readme is for v2 and deprecated.

To Reproduce

from ad_api.api.reports import Reports

from config import AmazonAdAPI

my_credentials = AmazonAdAPI.get_credentials()



params = {
        "name":"",
        "startDate":"2023-04-01",
        "endDate":"2023-04-08",
        "configuration":{
            "adProduct":"SPONSORED_PRODUCTS",
            "groupBy":["campaign","adGroup"],
            "columns":["adGroupId","campaignId", "impressions", "clicks", "cost", "purchases1d", "purchases7d", "purchases14d", "purchases30d","date"],
            "reportTypeId":"spCampaigns",
            "format":"GZIP_JSON"
        }
    }

result=Reports(credentials=my_credentials).post_report(**params)

Expected behavior
I've tried a few different scenarios but keep getting stuck on different errors.
