Is JSON::Validator allows to use nullable and oneOf keyword?

[avkhozov]

• JSON::Validator version: 4.13
• Perl version: 5.22
• Operating system: Ubuntu 20.04.1 LTS

Steps to reproduce the behavior

I have a test script with schema where object property use oneOf keyword and one of $ref have nullable attribute.

use JSON::Validator;

my $schema = JSON::Validator->new->schema('data://main/spec.json')->schema;

my $body = {exists => 1, value => {name => undef}};

my @errors = $schema->validate_response([get => "/test"], { body => \&body });
warn "@errors" if @errors;

sub body {$body}
