Updates the text-encoding-utf-8 dependency to version 1.0.2, which now supports ESModules in node >= v8.6.0 via the --experimental-modules flag.

We currently support ESModules in node in the main apache-arrow package, but need our dependencies to also expose ESModule forms as well. I have also issued a PR to flatbuffers to add ESModules support, and are using a temporary fork of flatbuffers in my github until that PR is merged.

This PR enables the following workflow:

// file - index.mjs
// run via `node --experimental-modules index.mjs`
import util from 'util';
import * as fs from 'fs';
import { Table } from 'apache-arrow';
(async () => {
  const buffer = await util.promisify(fs.readFile)('simple.arrow');
  console.log(Table.from([buffer]).toString());
/*
 foo,  bar,  baz
   1,    1,   aa
null, null, null
   3, null, null
   4,    4,  bbb
   5,    5, cccc
*/
})();
