feat: change tslib from direct dependency to peerDependency (#1132)
feat: change tslib from direct dependency to peerDependency (#1132)

BREAKING CHANGE:

We no longer directly have a direct depedency on `tslib`. Instead it is now listed a `peerDependency`.

Users not using the CLI will need to manually install `tslib` via;
```
yarn add tslib
```
or
```
npm install tslib --save
```
