Release 2.2.202130

This is a bugfix release to address Issue #10, and also updates all dependencies. Thanks to @mazz for the bug report!

Issue #10 resulted in a very high likelihood (every time?) that the "split" file (-s) option would use the same input text (line), the last one, for all speech generation. It would be an entirely new generation, but it would use the same input text rather than the earlier line or lines.

As always, pre-built binary executables are also provided below for Windows, Linux, and MacOS.
For MacOS and Linux executables, don't forget to mark them as executable with chmod -x ... before use.
MacOS users will probably also need to "bless" the executable using the Security & Privacy system preference applet.
