Problem with file upload, corrupted files

## Bug Report

**Current Behavior**

Using serverless-offline with Python and Flask with file upload corrupts the file.

Deployment to AWS Lambda resolves the issue. I had the same error on AWS prod env, but I have resolved it by setting `*/*` for `binaryMediaTypes`. It seems like the serverless-offline ignores `binaryMediaTypes` setting.

Upload of file via this CURL command fails with the following exception:
```bash
curl -X "POST" "http://localhost:3000" \
-H 'Content-Type: multipart/form-data' \
-F "file=@/Users/davidpivonka/Book1.xlsx"
```
This is an example of an uploaded file: [Book1.xlsx](https://github.com/dherault/serverless-offline/files/10371653/Book1.xlsx). Every file except plain .txt file is corrupted.
