- **parser:** ParseError is changed from index,loc:{line,column}
  to start,end,range:[start,end],loc:{start:{line,column},end:{line,column}}
  just like what we have on AST node when options ranges and loc is
  turned on.
- drop support of Nodejs < 18
- only distribute following files:
  dist/meriyah.cjs
  dist/meriyah.mjs
  dist/meriyah.min.mjs
