Fix invalid path error on pip install for Windows

[deton]

Problem

pip install fails with an invalid path error on Windows
because of a file name that contains the reserved character *.

pip install git+https://github.com/nsh87/regressors.git

ERROR: Could not install packages due to an OSError: [Errno 22] Invalid argument: 'C:\\Users\\x\\AppData\\Local\\Temp\\pip-req-build-l9tmy2kt\\.editorconfig*.py'

Cause

*(asterisk) character cannot be used in file name on Windows.

Solution

This pull-request removes .editorconfig*.py.
(.editorconfig file has same content.)
