product_finder ignores "dealType" parameter

[cf-dtrznadel]

Hello,

When I am trying to get products for specific category, I am receiving all the products (ignoring dealType filter):

keepa code (returns over 3k ASINs):
product_parms = {"categories_include": ["7676395011"], "dealType": ["countdown_ends_in", "early_access_with_prime"], "perPage": 10000, "page": 0, "perPage": 10000} products = keepa_api_client.product_finder(product_parms)

With requests library (returns 4 ASINs):

`selection_criteria = {
"categories_include": ["7676395011"],
"dealType": ["countdown_ends_in", "early_access_with_prime"],
"page": 0,
"perPage": 10000
}

query_params = {
"key": api_key,
"domain": 1,
"selection": json.dumps(selection_criteria)}
response = requests.get(base_url, params=query_params)`

keepa version 1.4.0
