saspy 4.3.0 on Python PyPI

[4.3.0] - 2022-05-17

New Per a user request, I added the ability to use sshpass with the STDIO over SSH access method.
This allows you to authenticate with user/pw instead of having to use rsa keys (passwordless shh). There
are now two new keys (see the doc) for providing the path to the sshpass executable and the parameters to use.
The ssh key and other keys for this configuration stay the same.

Enhanced The sd2df methods require multiple interactions (code submissions) to the SAS server and if any of these
intermediate steps fail or have some issue, then the method invocation fails. But, I wasn't catching these intermediate
problems which could cause non-obvious exceptions and tracebacks which were confusing. I've added code to catch failures
for these intermediate steps and throw a more clear exception if that happens. Nothing about how the methods works has
changed, just better error handling.
Enhanced The code that checks for an 'ERROR:' in the log and issues a warning to alert you to look to see what the
error was, wasn't only looking for it to start in column 1 of the log. So, it could pick up 'ERROR:' in a comment in the
code or anywhere in the log. I've enhanced this to limit false positives by only flagging 'ERROR:' starting in the first
column of the LOG.
Tweak Fixed a typo in an error message.

Fix The COM Access Method had a bug where the encoding was being used to transcode HTML results returned to
SASPy when it shouldn't, since the HTML results are already utf-8. Other code paths retrieving data from SAS did need to
use the provided encoding for transcoding from SAS Session encoding to utf-8. So, this one path was changed to not try to
transcode the HTML results. This was a fix for issue 454.
