fix: replace attrdict

[Kingfish404]

• For attrdict, the original library is now no longer maintained and there are some warning on python3.7.
  So I replaced it with reference to accessing-dict-keys-like-an-attribute

All tests pass for python3.7 and python3.6, also work fine in internal projects.

Warning: on python3.9 and upper, some tests fail:

Split from #23 because attrdict's replace could case fault and need more test.
