Check path safety optionally instead of always

[davibicudo]

Hi,

When instantiating a resource, would it be possible to check the path for safety only optionally?
Refering to:

datapackage-py/datapackage/resource.py

Line 806 in c6f479d

if not helpers.is_safe_path(path[0]):

In my use case, we have a project with files stored on the local server and I'd like to better manage these files and perform data validation for internal purposes. This means what I'm doing is intended for a safe environment, not for any customer application. In this case, I'd like to be able to access the shared datasets from the absolute path, which is currently not possible.
Would it be possible to add an argument to the Datapackage instance allowing absolute paths?
Or maybe there is a better way of doing this which I'm not aware of?

Thank you!

I just realized this is already an open issue at #171
Sorry for the duplicate.
