Bug: set-interval-async typings are missing

[LastSandwich]

The bug

Typings for set-interval-async are not installed and the npm run build fails

src/Client.ts(4,54): error TS7016: Could not find a declaration file for module 'set-interval-async/dynamic'. 'C:/src/JSPrismarine/packages/client/node_modules/set-interval-async/dynamic/index.js' implicitly has an 'any' type.
  Try `npm i --save-dev @types/set-interval-async` if it exists or add a new declaration (.d.ts) file containing `declare module 'set-interval-async/dynamic';`

To Reproduce

1. Clone the repo https://github.com/JSPrismarine/JSPrismarine.git.
2. npm i
3. lerna bootstrap
4. npm run build

Expected behavior
Build should complete successfully

Additional
Definitely Typed typings exist for version 1 of set-interval-async and appears to be compatible.
I added "@types/set-interval-async": "^1.0.0" to package.json of src\packages\client and the project now builds.
