FormerlySerializedAs is not respected when parsing arrays

[trymoto]

Hello!
I've had issue with TryDeserialize assigning default values to fields marked with FormerlySerializedAs.

I have a following json structure:

"[
    {
        "public_name": "Name"
    },
    {
        "public_name": "Name2"
    }
]"

Then i use struct type to pass into Deserialize:

[Serializable]
public struct UserDTO
{
    [FormerlySerializedAs("public_name")]
    public string publicName;
}

and the wrapper i'm using is from example StringSerializationAPI in readme:

StringSerializationAPI.Deserialize(typeof(UserDTO[]), jsonString)

However, on the other end i get array with default values

publicName = {string} null

Do i have to create fsDirectConverter for that?
