saspy 4.3.5 on Python PyPI

[4.3.5] - 2022-10-17

Tweak Had a PR with fixes to Doc; mostly typos and consistent use of terms. Also fixed a broken link.

Fix Fix for leaked resources. The pipes that are created between subprocess and Python were not being
released prior to subtask termination. This results in a resource leak that is identified when running with
settings that report these issues. I clean this up in both the IOM and STDIO access methods, they each had
similar concerns. No programming changes required.
Fix Fix for issue 487 where, in the df2sd() method, there was data that contained the data step
termination string which resulted in the data step, which was retrieving the data and writing it to the SAS
data step, terminating prior to processing all of the data and then SAS would take the rest of the stream
as SAS code, which fails miserably and consumes memory with all of the errors going to the log. It also
terminates the connection to the client. I've also added code in the java client to catch this kind of
failure so it wouldn't hang, like it was. So this is addressed and fixed in this release, and requires no
programming changes.
