/**
* Create a new Parameter using an associative array of data. The array can contain the following information:
* - name: (string) Unique name of the parameter
* - type: (string|array) Type of variable (string, number, integer, boolean, object, array, numeric,
* null, any). Types are using for validation and determining the structure of a parameter. You
* can use a union type by providing an array of simple types. If one of the union types matches
* the provided value, then the value is valid.
* - instanceOf: (string) When the type is an object, you can specify the class that the object must implement
* - required: (bool) Whether or not the parameter is required
* - default: (mixed) Default value to use if no value is supplied
* - static: (bool) Set to true to specify that the parameter value cannot be changed from the default
* - description: (string) Documentation of the parameter
* - location: (string) The location of a request used to apply a parameter. Custom locations can be registered
* with a command, but the defaults are uri, query, header, body, json, xml, postField, postFile.
* - sentAs: (string) Specifies how the data being modeled is sent over the wire. For example, you may wish
* to include certain headers in a response model that have a normalized casing of FooBar, but the
* actual header is x-foo-bar. In this case, sentAs would be set to x-foo-bar.
* - filters: (array) Array of static method names to to run a parameter value through. Each value in the
* array must be a string containing the full class path to a static method or an array of complex
* filter information. You can specify static methods of classes using the full namespace class
* name followed by '::' (e.g. Foo\Bar::baz()). Some filters require arguments in order to properly
* filter a value. For complex filters, use a hash containing a 'method' key pointing to a static
* method, and an 'args' key containing an array of positional arguments to pass to the method.
* Arguments can contain keywords that are replaced when filtering a value: '@value' is replaced
* with the value being validated, '@api' is replaced with the Parameter object.
* - properties: When the type is an object, you can specify nested parameters
* - additionalProperties: (array) This attribute defines a schema for all properties that are not explicitly
* defined in an object type definition. If specified, the value MUST be a schema or a boolean. If
* false is provided, no additional properties are allowed beyond the properties defined in the
* schema. The default value is an empty schema which allows any value for additional properties.
* - items: This attribute defines the allowed items in an instance array, and MUST be a schema or an array
* of schemas. The default value is an empty schema which allows any value for items in the
* instance array.
* When this attribute value is a schema and the instance value is an array, then all the items
* in the array MUST be valid according to the schema.
* - pattern: When the type is a string, you can specify the regex pattern that a value must match
* - enum: When the type is a string, you can specify a list of acceptable values
* - minItems: (int) Minimum number of items allowed in an array
* - maxItems: (int) Maximum number of items allowed in an array
* - minLength: (int) Minimum length of a string
* - maxLength: (int) Maximum length of a string
* - minimum: (int) Minimum value of an integer
* - maximum: (int) Maximum value of an integer
* - data: (array) Any additional custom data to use when serializing, validating, etc
* - format: (string) Format used to coax a value into the correct format when serializing or unserializing.
* You may specify either an array of filters OR a format, but not both.
* Supported values: date-time, date, time, timestamp, date-time-http
* - $ref: (string) String referencing a service description model. The parameter is replaced by the
* schema contained in the model.
*
* @param array $data Array of data as seen in service descriptions
* @param ServiceDescriptionInterface $description Service description used to resolve models if $ref tags are found
*
* @throws InvalidArgumentException
