Wrong type when binary file in the request

[ssduman]

Hello,

If we send a file in binary form from Postman, p2o threats it as text/plain. Here is the example Postman and p2o result:

{
	"info": {
		"_postman_id": "daeaed7e-5dee-4aa8-8828-3280afb2b11a",
		"name": "Raw Body",
		"description": "Mi super test collection from postman",
		"schema": "https://schema.getpostman.com/json/collection/v2.1.0/collection.json"
	},
	"item": [
		{
			"name": "Test Raw Body - File",
			"request": {
				"method": "POST",
				"header": [],
				"body": {
					"mode": "file",
					"file": {
						"src": "AuthBasic.json"
					}
				},
				"url": {
					"raw": "https://api.io/file",
					"protocol": "https",
					"host": [
						"api",
						"io"
					],
					"path": [
						"file"
					]
				}
			},
			"response": []
		}
	],
	"event": [
		{
			"listen": "prerequest",
			"script": {
				"type": "text/javascript",
				"exec": [
					""
				]
			}
		},
		{
			"listen": "test",
			"script": {
				"type": "text/javascript",
				"exec": [
					""
				]
			}
		}
	]
}

result:

openapi: 3.0.0
info:
  title: Raw Body
  description: Mi super test collection from postman
  version: 1.0.0
servers:
  - url: https://api.io
paths:
  /file:
    post:
      tags:
        - default
      summary: Test Raw Body - File
      requestBody:
        content:
          text/plain: {}
      responses:
        '200':
          description: Successful response
          content:
            application/json: {}

I believe this behavior due to this line: https://github.com/joolfe/postman-to-openapi/blob/master/lib/index.js#L180

case 'file':
  content = {
    'text/plain': {}
  }
  break

And also, postman and OpenAPI support this: https://spec.openapis.org/oas/v3.0.3.html#considerations-for-file-uploads Thanks in advance.
