Remove "byte" and "binary" formats altogether.

Instead of just deprecating.  The "content*" keywords now
cover these use cases.

-Use of `byte` or `binary` is discouraged, and later versions of this specification may remove them from this list.  They SHOULD be replaced with the JSON Schema keywords `contentEncoding` or `contentMediaType` as follows:
-

-* replace `"format": "binary"` with  `"contentMediaType": "application/octet-stream"` or an appropriate specific media type

-<a name="encodingContentType"></a>contentType | `string` | The Content-Type for encoding a specific property. Default value depends on the property type: for `string` with a `contentMediaType` - `contentMediaType`; for other primitive types – `text/plain`; for `object` - `application/json`; for `array` – the default is defined based on the inner type. The value can be a specific media type (e.g. `application/json`), a wildcard media type (e.g. `image/*`), or a comma-separated list of the two types; **Deprecated:** for `string` with `format` being `binary` – `application/octet-stream`.

This property SHALL be ignored if the request body media type is not a `multipart`.
 <a name="encodingStyle"></a>style | `string` | Describes how a specific property value will be serialized depending on its type.  See [Parameter Object](#parameterObject) for details on the [`style`](#parameterStyle) property. The behavior follows the same values as `query` parameters, including default values. This property SHALL be ignored if the request body media type is not `application/x-www-form-urlencoded` or `multipart/form-data`. If a value is explicitly defined, then the value of [`contentType`](#encodingContentType) (implicit or explicit) SHALL be ignored.
 <a name="encodingExplode"></a>explode | `boolean` | When this is true, property values of type `array` or `object` generate separate parameters for each value of the array, or key-value-pair of the map.  For other types of properties this property has no effect. When [`style`](#encodingStyle) is `form`, the default value is `true`. For all other styles, the default value is `false`.

If a value is explicitly defined, then the value of [`contentType`](#encodingContentType) (implicit or explicit) SHALL be ignored.
