[#1] Rewrite from scratch

- Use` rollup-plugin-prettier` as example
- Replace `jest` with `ava`
- Generate TypeScript declaration files. Added `tsconfig.json` for that purpose
- Wire up `prettier` and enhance ESLint configuration
- Remove `.travis.yml` because of switching to GitHub Actions
- Add `jsconfig.json` form improved JS typing
- Set `rollup` and `eslint` as peer dependencies
- Update dependencies

+# rollup-plugin-eslint-bundle changelog
+
+## 6.0.0 - 2021-01-24
+* Rewrite from scratch for latest `rollup` and `ESLint`
+* Replace `jest` with `ava`
+* Require Node.js version >= 12
+* Set `rollup` and `eslint` as peer dependencies
+* Generate TypeScript declaration files.
+
+## 5.0.2 - 2018-11-02
+* Update dependencies
+
+## 5.0.1 - 2018-07-15
+* Fix for case when fix doesn't produce output
+* Fixes for ESLint 5.x
+* Disable tests for source mapping. For some reason rollup returns the same 'mappings' for fixed and not fixed code even though the plugin produces different source maps
+* Update dependencies
+
+## 5.0.0 - 2018-01-21
+* Rewrite to verify and fix the bundle instead of imported files
