Do not do type conversion at encoding time by default anymore.

Until now Leshan used by default a kind of magic converter.
This converter was used LwM2mNodeEncoder to fix LwM2mResource which would used a different
ResourceModel.Type than the one defined in the ResourceModel.

This magic conversion was mainly used to correct value which came from the leshan-server-demo UI...
So this does not make so much sense to keep this behavior by default.

So now the default converter is a NoValueConverter which do not do any converstion but raise an exception, if type in resource does not match the model.

If you want to keep the previous behavior you need to duplication class from leshan-server-demo : MagicLwM2mValueConverter and create your server like this :

LeshanServerBuilder builder = new LeshanServerBuilder();
builder.setEncoder(new DefaultLwM2mNodeEncoder(new MagicLwM2mValueConverter()));
LeshanServer server = builder.build();

What do you think of keeping the MagicLwM2mValueConverter in the leshan-core package?

This NoValue name is bit confusing. It is more a NoConversionConverter 😄.
CheckTypeConverter?

I renamed it by LwM2mValueChecker

I prefer to not keep in in leshan-core as it is only needed for leshan-server-demo
