create-multi-lib: write UI components once, compile everywhere

Описание: Mitosis (https://github.com/BuilderIO/mitosis) is a fantastic project. It allows you to "write once, run everywhere" in the sense that you can write a UI component and have it compiled to a React component for use in a React project, a Svelte component for use in a Svelte project, and so on. It does not, however, support bundling.

create-multi-lib (run like so `npx create-multi-lib your-lib-name) is an attempt to contribute a much needed bundling-layer on top of Mitosis.

It also comes with E2E testing included, and your resulting packages include type-declarations.
