What does this PR do?

Related on #55

The default UTF-8 encoding of Python 3 is belong users system, and in windows, it can not be always 'utf-8' encoding.

So I fixed it always read with UTF-8 encoding.

It works fine, in my environment

$ pip install -e .

python and pip version is as you can see the following:

$ pip --version
pip 22.1.1 from C:\Python38\lib\site-packages\pip (python 3.8)

you know, CI tells it have only one error but I can not understand that.

style / mypy-py3 (ubuntu-latest, 3.7) (pull_request) Failing after 55s — mypy-py3 (ubuntu-latest, 3.7)

>>> torchscan/modules/memory.py:228: error: Unsupported operand types for // ("int" and "None")  [operator]

but I did not fix it :/

@joonas-yoon I see, so that's because of the latest pip version!

About the CI failure, don't worry, it's unrelated 👍
