1. Is this request related to a challenge you're experiencing? Tell me about your story.

I need to send XLSX and receive PDF response in HTTP Request node. It calls AWS API Gateway. APIGW requires binary responses are base64 encoded. It seems that Dify has no base64 decoding capablity now.

2. Additional context or comments

/api/core/workflow/nodes/http_request/entities.py
I think updating Response class to auto-detect encoding will be good.
