Requests attempts to autoencode PUT request on line 63 of client.py

[devyzr]

Currently I'm using the BrickFTP python client to upload files to BrickFTP, the issue arises when I attempt to upload a file containing the character "\u2019", I get the following error:

UnicodeEncodeError: 'latin-1' codec can't encode character '\u2019' in position 89154: Body ('’') is not valid Latin-1. Use body.encode('utf-8') if you want to send it encoded in UTF-8.

I already tried specifying the uft-8 encoding despite it being the default encoding the upload function on line 48 of client.py uses to no avail. After some research I found that the previously mentioned error is because the Requests library attempts to auto-encode what it's uploading based on the first 127 characters of the data. See: https://stackoverflow.com/questions/41030128/str-encoding-from-latin-1-to-utf-8-arbitrarily

I was able to solve this by modifying line 63 of client.py from this:
resp = requests.put(upload_uri, data=input_file.read())

to this:
resp = requests.put(upload_uri, data=input_file.read().encode(encoding))

I will be submitting a PR shortly.
