Ignore specific files/lines when ignoring issues about deptry

[fpgmaas]

Great idea, I think this would be very useful! Given #398, it might make sense to implement this similar to ruff as well. ruff has the following flags:

  --ignore <RULE_CODE>
      Comma-separated list of rule codes to disable
  --per-file-ignores <PER_FILE_IGNORES>
      List of mappings from file pattern to code to exclude

In our case, we could have the following flags:

--ignore
--per-rule-ignores
--per-file-ignores

--ignore can be used to ignore a rule (DEP001, DEP002, etc) in the entire codebase. e.g.

deptry . --ignore DEP001,DEP002

--per-rule-ignores can be used to skip certain packages or modules for specific rules, e.g: Ignore matplotlib for DEP002.

deptry . --per-rule-ignores DEP001=matplotlib,DEP002=pandas|numpy

The --per-file-ignores can be used to skip checking for specific rules for specific files. Here, we might want to give functionality to both ignore a rule completely per file, and only ignore it for specific modules/dependencies:

deptry . --per-file-ignores DEP001=path/to/file1.py,DEP002=path/to/file2.py:pandas|numpy

This would ignore DEP001 completely in file1.py, and it would ignore pandas and numpy for DEP002 in file2.py.

Curious for your thoughts on the proposal!

@kenibrewer sorry, those have not been implemented yet!

@fpgmaas I think a good part of this issue was addressed in 0.12.0. Have the in-file
import tomllib # deptry: ignore[DEP001]
style ignores already been added as well or is that still outstanding?
