* chore(lint): don't allow excess trailing newlines This enforces that files should not end with blank lines (i.e. more than one trailing newline). The `eol-last` rule (inherited from airbnb's config) already enforces that files end in at least one trailing newline, so adding this rule enforces that it ends in exactly 1. See https://eslint.org/docs/rules/no-multiple-empty-lines and https://eslint.org/docs/rules/eol-last for more information. Inspired by #809. * add maxBOF
