fix(lib): Support large body uploads with repeated read callbacks

When uploading larger amounts of data, cURL will call the read
callback incrementally multiple times to receive all the expected
data.

Previously if the size of the data to upload exceeded the size of the
initial buffer provided by cURL, the write (and thus the request)
would fail.

This changes the logic to write the data in chunks of a size that are
acceptable to cURL.
