Deptry fails to parse jupyter notebooks with special syntax and line continuation characters

[jmbond]

When parsing jupyter notebooks that uses magic functions (starting with %), call outs to shell (starting with !) or line continuation characters (lines ending with \), deptry fails.

These parsing errors can be seen by running the sample notebooks in this repo. There I have created three notebooks that showcase the errors, one containing a magic function, one calling out to shell, and one using a continuation character. The warnings are provided below:

$ deptry -ddg dev .
Scanning 4 files...
Warning: Skipping processing of notebook-exclamation.ipynb because of the following error: "SyntaxError: invalid syntax. Got unexpected token '!' at byte offset 0".
Warning: Skipping processing of notebook-line-continuation.ipynb because of the following error: "SyntaxError: invalid syntax. Got unexpected token Newline at byte offset 9".
Warning: Skipping processing of notebook-percent.ipynb because of the following error: "SyntaxError: invalid syntax. Got unexpected token '%' at byte offset 19".

pyproject.toml: DEP002 'numpy' defined as a dependency but not used in the codebase
pyproject.toml: DEP002 'jupyter' defined as a dependency but not used in the codebase
Found 2 dependency issues.

For more information, see the documentation: https://deptry.com/

I would expect deptry to be able to parse these notebooks.

My system:
