Describe the enhancement

Add the option headers for this http(s) request

Use cases

Sinds i am using a raspberry pi 4 for my home assistant and esphome, compiling takes a lot of time.
so I am working that the firmware gets build by github actions.

the github actions in a private repo (of course) create a release with the firmware files in it. but when you want to download the firmware you need to set the header: "Accept: application/octet-stream" else you get an overview the downloadable assets. and not the download it self.

example url:
https://api.github.com/repos/<username>/<repo>/releases/assets/<number>

headers you can set request_headers in the http but not in the http_request ota.

Anything else?

I currently trying but i think the http update with ota from github is to much for a esp8266.

http_request:
  verify_ssl: false

external_components:
  - source: github://DJJo14/esphome@ota_http_add_header
    components: [http_request, http_request/ota]
    refresh: 1s

api:
  encryption:
    key: "1234"

  actions:
    - service: http_ota_header
      variables:
        url: string
        mdfive: string
      then:
        - ota.http_request.flash:
            url: !lambda 'return url;'
            md5: !lambda 'return mdfive;'
            request_headers:
              Accept: application/octet-stream
              authorization: Basic 1234==

but i get:

I can also be an other error, i see similar bug reports.

the github://DJJo14/esphome@ota_http_add_header has currently extra debug code and the buffers are lager
