Updates Typescript to >=2.9

[ritave]

Typescript 2.9 and later changes on how the JSON files are imported. Due to lack of time we've decided to freeze the version to <2.9.0 but in the future we'd be happy to updated it to the newest version.

Work needed to be done:

• [ ] Update all package.json
• [ ] Add support for esModuleInterop
• [ ] Update all packages to use esModuleInterop
• [ ] Add support for resolveJsonModule
• [ ] Update all imports to use esModuleInterop
• [ ] Add support for declarationMap
• [ ] Fix all dependencies

Some initial work was done in the ritave/fix-ts branch. It's a good starting point
