Don't convert data={"key": [bytes|bytearray]} cases into strings

[mertyildiran]

Related to #1539

In case of a value in the data keyword argument is bytes or bytesarray, converting them to str was not the original behavior. I think it's forgotten to cover these cases in #1539 so this PR covers bytes|bytearray cases.

To replicate the issue:

import httpx

with open('path/to/some_image.png', 'rb') as file:
    image_file = file.read()
    httpx.post('http://localhost:800/some_path', data={'example': image_file})

P.S. The binary data is being sent as is in the requests package and in the versions of httpx before 0.18.0.

Hi, thanks for your clarification, I would like to confirm when I open a file and put it in a request, I should pay attention to manually set the read mode to be 'rb', because when I work with string it cannot work like you said.
