   Previously, when users wanted to create their own headers, they could do something like this:

   apify_client = ApifyClient(...)
   apify_client.http_client.httpx_client.headers.update(custom_headers)
   

   After changing to impit, this no longer seems possible. Setting custom headers is not uncommon and should be supported by the client without any problems.

   Now, when they want to change headers, they have to resort to monkeypatching and manipulating private methods, for example:

   custom_header = {"bla": "blo"}
   
   client=ApifyClientAsync(token="asd")
   orig_prepare_request_call = client.http_client._prepare_request_call
   
   def wrapped_prepare_request_call(*args, **kwargs):
       headers, _parsed_params, data = orig_prepare_request_call(*args, **kwargs)
       headers.update(custom_header)
       return headers, _parsed_params, data
   
   client.http_client._prepare_request_call = wrapped_prepare_request_call
