[BUG] RPC fails to process ready event as `premium_type` is null.

[jacksonrakena]

Describe the bug DiscordRPC fails to process a DISPATCH event because it fails to convert a null value for premium_type to the PremiumType enum.

To Reproduce I can only reproduce this behavior with specific users, but I believe that this issue only occurs on users without Nitro (where premium_type should be 0, but for some reason is null.

Expected behavior DiscordRPC successfully parses the event.

Desktop (please complete the following information):

• OS: Windows 11, 64-bit
• Framework: .NET 6 (net6.0-windows)
• Library Version: 1.0.175

Additional context I patched DiscordRPC to add a ? operand to the PremiumType Premium field in User.cs and that resolved this issue, although this would change the DiscordRPC API spec and could impact other users.
