backport v2.0.2 bugfix to v1.*

a major bug was fixed in 2.0.2 -- this backport fixes the same issue so
that projects using numpy >= 1.0.0 can still use it

* return pyproject to use numpy >= 1.0.0 and >= python3.8
* add python 3.8 back to test builds
* backport type annotations (Tuple and List) to meet lowest python version

Feature/24 release number from ci (#25)

update CI to use release tag for version number for publishing

including:
* change version number in pyproject.toml to 9.9.9
* update CI publish step to get the version number from release tag

update README with infor about installing using pip

Merge branch 'fix/setup_script' into develop

update project to Python3

Python3 introduced a distinction between strings and bytes.  This resulted in a problem when trying to save a numpy array into an io.StreamIO object.

The code has now been adapted to use io.BytesIO.

Additionally:
* update print statements to Python3
* change init file for proper importing
* change error catch to fit python3 syntax
* update class send method to use BytesIO
* update class recieve method to use BytesIO
* change shebang to python3
* add requirements file for example code
* change variables names to be clearer
* add logging and custom errors to module
* update license date
* add example code for arbitrary numpy array
