Fork new sequelize-ts to support Sequelize v6

[hsluoyz]

New fork: https://github.com/node-casbin/sequelize-ts

We have an urgent need to support Sequelize v6. We have to fork it because the current PRs are not handled very quickly. Currently we are testing this PR: #868 (comment) but encountered some issue.

I also saw the current PR doesn't use CI to run all tests. Maybe need to add a Travis CI or GitHub Actions to the repo.

Hope somebody also interested in it can join us, thanks!

@hsluoyz Instead to create a fork, we should continue to work on this repo, sequelize-typescript@2.0.0 has been released, so it supports sequelize >= 6.0.0. 😄

@divlo hi, did v2.0.0 release resolve this issue? #868

I asked this because we encountered a similar issue here: node-casbin/sequelize-adapter#34

I also tried by myself but still has error even for sequelize 6.2.0:

    "sequelize": "^6.2.0",
    "sequelize-typescript": "^2.0.0"

$ jest --forceExit

        The last overload is declared here.

Can you help me have a look? Thanks!

@hsluoyz Hey, I don't know if it has been fixed, but please open issues/PR so we can improve sequelize-typescript together.
Also you could provider "steps to reproduce so we can fix it easier".
