Update pydsdl as requirement to 1.4

[jxltom]

Since https://github.com/UAVCAN/pyuavcan/issues/103 is solved by https://github.com/UAVCAN/pydsdl/pull/39, pydsdl as requirement can be locked to 1.4.

Dependency nunavut also requires pydsdl 1.4, this PR solves the conflict.

Please also freeze pytest-asyncio == 0.10 to fix the test suite. It broke because the recently released version is incompatible with PyTest v4, and we can't upgrade it because of https://github.com/UAVCAN/pyuavcan/issues/95.

A better solution would be to replace pkg_resources with importlib in Nunavut and then upgrade PyTest here to the latest version. Maybe you could do that instead?

[jxltom]

The tests are fixed, it looks like including all python files as tests source by python_files = *.py triggers the issue.

[pavel-kirienko]

This is certainly not the root cause because the filename should have nothing to do with it. Your fix silently removes unit tests that are located in files named without a leading underscore so this is undesirable.

[jxltom]

There are still 126 tests left, no tests are removed by this PR. It is better to name test files with prefix test_ in the further development.

My suspect is that including all files in tests might also includes setup.py or whatever which is not tests at all trigger the issue, but I have no time to dig it out

[pavel-kirienko]

test_*.py won't work because some tests are embedded directly in the implementation files to enhance test locality. This is an intentional design decision and I currently see no reason to change it. The underscore prefix would break the tests in the bootloader branch. The correct fix for the above problem is to fix Nunavut.

[jxltom]

OK, I don't know there are embbeded tests in source dir in other branch.

I will check your suggestions.

This fix is also required for yukon, because it depends on nuvanut (needs 1.4.0) and pyuavcan (needs 1.2.0). Without it it's not possible to manage dependencies with pip.

[jxltom]

Just have some time to continue the PR. Yeah you are right. The pkg_resources is not well supported after pytest 4.6.0 as suggested here https://github.com/pytest-dev/pytest/issues/5392 and https://github.com/pytest-dev/pytest/commit/13f02af97d676bdf7143aa1834c8898fbf753d87. It is better to replace pkg_resources with importlib_resources and importlib-metadata

However, I'm not sure when I have time to do ths, so in this PR, I just pin the pytest as well as its related requirements to v4.6 temporarily.
