chore

• drop support of Nodejs < 18 (829835e)
• reduce dist files to esm, cjs, and umd (962af5f)

Features

• lexer: support regexp v flag (unicodeSets) (1d9a1ee)
• parser: expose start/end/range/loc:{start,end} to ParseError (27691df), closes #156
• parser: implement lexical analysis of private identifiers (66217a1), closes #322
• parser: support arbitrary module namespace names (e43e93c), closes #200 #214

  ECMA spec, and ESTree spec. No point to make it an optional feature.
• 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
  dist/meriyah.umd.js
  dist/meriyah.umd.min.js
  All transpiled with target: "ES2021"
