Optional support for opt-in public member serialization?

[MaxSavenkov]

When switching to MemoryPack from another serialization solution, it would be useful to have an option to avoid automatically serializing all public members of MemoryPackable classes, because marking them all with MemoryPackIgnore is too much work and makes code ugly. I propose to add an option to MemoryPackable attribute, or, if it's too much work for generator, maybe add a separate MemoryPack.OptIn attriubte?

Is it possible in MemoryPack not to serealize the base class fields?

[MaxSavenkov]

@PragmaGame With a hack. You can declare those fields as "private new" in derived classes, and don't mark them with MemoryPackInclude. This should prevent their serialization, I think. But in general, this is very suspicious, so you might want to rethink your hierarchy if you really need this.
