consider default name when validating

[caarlos0]

Hey! Thanks for this, amazing project!

I have a small issue which I think other people will have as well, for instance, consider this struct:

type Foo struct {
  Foo string `yaml:",omitempty"`
  Bar string `yaml:"notBar"`
}

If I validate it using snake case, both fields should fail, as the first will be, by default Foo and the second one is in camel case.

Would be nice if either the default name is considered or if we could disallow not naming the field.

Cheers!

Hello,

I think I understand the use case, I will try to add a new option for this.
