S3Boto3StorageFile's readlines always return bytes even if mode is set to rt

[nl-emmanuellodovice]

Sample code

with default_storage.open(path, 'rt') as file:
     print(file.readlines())

you get something like

[b'"Number","Name","Date","Datetime"']

I had the same issue.
Paramiko RSAKey depends on readlines function with mode 'r', but as it returns always bytes, it throws error.
