Add Jupyter Lite support for SDK

[knajjars]

How to reproduce:

1. Go to: https://cohere-ai.github.io/jupyter_lite/repl/?toolbar=1&kernel=python
2. Add the following code snippet

   import piplite
   await piplite.install("cohere")
   import cohere
   co = cohere.Client('<your_prod_api_key>')
   prediction = co.generate(
   model='xlarge-20220301',
   prompt='The table lists the following professions as artistic careers:\n1. Painter\n2.',
   max_tokens=50,
   temperature=1,
   k=0,
   p=0.75,
   frequency_penalty=0,
   presence_penalty=0,
   stop_sequences=[],
   return_likelihoods='NONE')
   print('Prediction: {}'.format(prediction.generations[0].text))

3. It fails due to the stdlib used for performing HTTP requests, which is not compatible with Pyodide (Python port for WASM)

Expected behavior:

1. We should support using the SDK in a Pyodide environment, by either allowing passing a custom http client or building a separate SDK for Pyodide.
