Unintended access to the filesystem

[GetPsyched]

The problematic line:

nexus/nexus/Freqlog/Definitions.py

Lines 40 to 41 in 3e6d11f

	# Create directory if it doesn't exist
	os.makedirs(os.path.dirname(DEFAULT_DB_PATH), exist_ok=True)

This is run when imported here:

nexus/tests/Freqlog/backends/SQLite/test_SQLiteBackend.py

Line 6 in 3e6d11f

from nexus.Freqlog.Definitions import BanlistAttr, CaseSensitivity, WordMetadataAttr

Even though the Definitions class isn't imported, it is executed since all the code in it is not inside some function, like __init__.

This causes an issue in my Nix derivation of it during the test phase where it tries to access the filesystem since during a build, the HOME directory does not exist. This will likely happen in any package manager that runs tests in a homeless system. I've temporarily fixed this by adding export HOME=$TMPDIR in the derivation; however a fix for this should be done in here.

A solution would be to create an __init__
