[BUG] Imports removed from class scopes

[joaoe]

Describe the bug A clear and concise description of what the bug is.

Imports are incorrectly removed from class scopes.
Sometimes I use class scopes to keep imports contained when implementing multiple versions of the same interface

class TaskAdapter:
    def run(self, fn, *a, **kw):
        raise NotImplementedError

class ThreadAdapter(TaskAdapter):
    import threading

    def run(self, fn, *a, **kw):
        result = []
        fn = functools.partial(fn, *a, **kw)
        t = self.threading.Thread(target=lambda: result.append(fn()))
        t.start()
        t.join()
        return result[0]

class MultiProcessingAdapter(TaskAdapter):
    import multiprocessing
    
    def run(self, fn, *a, **kw):
        p = self.multiprocessing.Process()
        ....

class AsyncIOAdapter(TaskAdapter):
    import asyncio
    
    def do_something(self, fn, *a, **kw):
        loop = self.asyncio.new_event_loop()
        ....

pycln incorrectly removes these. Note that I also tried with autoflake and it works correctly and does not remove these imports.

To Reproduce Steps to reproduce the behavior:

1. Take this code snippet:

    class MyClass:
        import threading
        def run(self):
            assert self.threading
   
    assert MyClass.threading
    assert MyClass().threading

2. Run this Pycln command:

    $ pycln snippet.py
    a.py:2:4 'import threading' was removed! �
    a.py 1 import was removed! �
   
    All done! � �
    1 import was removed, 1 file was changed.

3. Error traceback or unexpected output (if present):

    Traceback (most recent call last):
      File "snippet.py", line 6, in <module>
        assert MyClass.threading
    AttributeError: type object 'MyClass' has no attribute 'threading'

4. Unexpected fixed code (if present):

    class MyClass:
    
        def run(self):
            assert self.threading

Expected behavior:

1. Description: A clear and concise description of what you expected to happen.

NOTHING. The code snippet should not be changed.

2. Expected fixed code (if present): SAME AS INPUT

   class MyClass:
       import threading
       def run(self):
           assert self.threading
   
   assert MyClass.threading
   assert MyClass().threading

Environment (please complete the following informations):

• Python Version: 3.9
• Pycln Version: 2.1.5
• OS Type: windows
