client.Users.GetPersonalBests throws a serialization exception if you use any of the optional parameters

[natronium]

i think it's constructing the URL incorrectly, getting a 404, and then failing to serialize that 404 json into an actual C# object

it looks like the code for UserClient.GetPersonalBests just concatenates the query parameters to the URL string without adding the necessary ? and &s, which doesn't generate a valid URL for the SRC API
