re-enable "findssh" project script

fixes #5

allows once again "findssh" script or "python -m findssh", which allows pipx to work as well.

Better use from Python scripts. Require Python >= 3.9

• Require Python >= 3.9 to make cancellable via "ctrl+c" and for general code quality
• give examples of and make function names better for use from other Python scripts

print address as they are detected, require Python >= 3.7

• emit (print) servers as soon as they're detected
• require Python 3.7 to clean up code

better setup robustness, metadata cleanup

v1.4.1

setup.py template, metadata

more robust app approach, CI Github Actions

use more robust packaged app directory layout

CI to GitHub Actions

code quality: dedupe, add matlab test, fix nuisance warnings

Used SelectorEventLoop instead of ProactorEventLoop on Windows, even for Python 3.8, to stop nuisance warnings

Deduplicate / modularize code

Add test (from Python) for Matlab API

Python >= 3.5 asyncio instead of ThreadPool

Using single-threaded asyncio vs. ThreadPool is twice as fast or more, using just a single thread and coroutines, all standard library for Python >= 3.5. The asyncio benefit is particularly noticeable on limited resource systems like Raspberry Pi.

Also, now Matlab works really fast as well calling the Python coroutine code

py38 OK, DOI badge

just a version bump

improve Python API, add Matlab

Added Matlab findssh.m to reuse the Python API.

Improved test coverage, corrected empty return from multi-threaded exec

py35 compatible, cleanup

v1.0.9
