GetAllCoinDataWithId Creates Exception if "genesis_date" is null

[GonzoKK]

Example is hydro coin

https://api.coingecko.com/api/v3/coins/hydro?localization=false

Quick fix is to Add ItemNullValueHandling to JsonContainerAttribute

[JsonObject(ItemNullValueHandling` = NullValueHandling.Ignore)]

Refer https://github.com/JamesNK/Newtonsoft.Json/issues/1429

Hi @GonzoKK

NullValueHandling added to genesis_date
