Wrong type for security fields

[Will Howell]

First thank you so much for this library - it's been a big time saver! 😄

I think I've found the following bugs:

interface OpenAPIObject {
 ... 
 security: SecurityRequirementObject // should be SecurityRequirementObject[]
}

interface OperationObject {
 ...
 security: SecurityRequirementObject // same thing here: SecurityRequirementObject[]
}
