Add additional guards to write_environment_packages.

[JoeZiminski]

This PR fixes #71 but adding additional guards to the environment logging (#62). The issue in the stacktrace was that

conda_env = os.environ["CONDA_PREFIX"].split(os.sep)[-1]
conda_exe = os.environ["CONDA_EXE"]
conda_list = subprocess.run(
[conda_exe, "list", "--json"],
capture_output=True,
text=True)

threw a json.JSONDecodeError because the subprocess call failed with

conda_list = CompletedProcess(args=['/Users/k2366861/miniforge3/bin/conda', 'list', '--json'], returncode=1, stdout='', stderr='Traceback (most recent call last):\n  File "/Users/k2366861/miniforge3/bin/conda", line 12, in <module>\n    from conda.cli import main\nModuleNotFoundError: No module named \'conda\'\n')

Somehow the base conda cannot access the Python package conda that conda.cli seems to require. I'm not sure how this is possible or exactly what is going on here. But, rather than try and understand the many weird and wondering packaging errors I'm sure we'll encounter, I just extended the try/except clauses to fail gracefully if such an error is encountered. One thing this does not do is log these errors, so it will be difficult to troubleshoot when fancylog fails to get the environment packages. However, I think this is preferable to including these fancylog-related stacktraces in the logging output?

This requires no documentation, but I did not test as I'm not sure the exact environment set up which led to the error. Maybe the person who encountered the error can try fancylog from this branch?

Thanks @JoeZiminski! TBC I couldn't replicate this, so far I've only seen it on @marcodallavecchia's system.

@marcodallavecchia if you get a chance to try this with brainreg, please do. Otherwise I suggest we just release it and keep an eye out for issues?
