PD005 erroneously flags arithmetic methods from other packages

Describe the bug PD005 is triggered when any module has a method named something like .add()

To Reproduce I noticed this while using the tarfile module. The tarfile module has a method named .add()

Here is the snippet. Flake8 triggered PD005 on both of the tar.add() calls.

tar = tarfile.open(tar_filename, "w")
tar.add(other_filename)  # <-- triggers PD005
for filename in filenames:
    tar.add(filename)  # <-- triggers PD005
tar.close()

Expected behavior I expect this to only be triggered when a method like .add() is called on a pandas object.

Additional context I expect that this applies to the comparison operators too (PD006). Any fix for PD005 should also be made for PD006 too.

Regarding the case for PD011 - .values, one check could be for the parentheses. I get a lot of false positives because I’m using both pandas and dictionaries. Looping through the values of the dictionary with .values() triggers PD011.

I’m not really familiar with the AST, so I don’t know if this is an easy check or not.

A quick hack (that could be optional for example) would be to check if pandas is imported in the file. Sure, it won’t work for a lot of cases, but for a lot of cases it also will work.
