Monorepo implemented with Turborepo

[volovyks]

• Project refactored to monorepo
• Now standards are a separate project
• Turborepo build system is used to orchestrate all the packages
• All link near-sdk-js and cd examples hacks were removed from build scripts
• Imports organized
• linting added to cli/ subproject

Such architecture will allow us to scale the project in the future, separate near-sdk-js to multiple packages, use 'caching', etc.

Awesome! This is very good project setup. Just one thing: examples are removed from ci, is it intentional?

@ailisp now, when you are running pnpm build from the root folder, Turbo will execute this command in each package (if it's available) in proper order: near-sdk-js, then standards, then examples and tests since they depend on the first two.
When you run pnpm test it will execute tests from all packages in parallel.

With this setup it is faster and more intuitive to have 1 CI job. Linting is also a part of it now. Check the steps and logs.
