chore: Convert Standard to eslint-config-standard (github#1328)

* chore: Move standard to ESLint config

* fix: auto-fix ESLint indent issues

* fix: ESLint prefer-regex-literals

* fix: ESLint array-callback-return

- .filter must return a boolean value
- .map replaced with forEach when the value isn't used

* fix: ESLint no-extra-semi
