[qiao]

Describe your bug.

Multiple arithmetic and comparison operations are not supported between two series.
Here's the list of operations that I have tested and the ones that support operations between two series are marked with the checkmark:

• add
• div
• divideBy
• minus
• modulo
• mul
• multiplyBy
• plus
• rem
• sub
• eq
• equals
• greaterThan
• greaterThanEquals
• gt
• gtEq
• lessThan
• lessThanEquals
• lt
• ltEq
• neq
• notEquals

The above checklist is generated with the following script:

const pl = require('nodejs-polars');
const a = pl.Series([1]);
const b = pl.Series([2]);

[
  'add',
  'div',
  'divideBy',
  'minus',
  'modulo',
  'mul',
  'multiplyBy',
  'plus',
  'rem',
  'sub',
  'eq',
  'equals',
  'greaterThan',
  'greaterThanEquals',
  'gt',
  'gtEq',
  'lessThan',
  'lessThanEquals',
  'lt',
  'ltEq',
  'neq',
  'notEquals'
].forEach((op) => {
  try {
    a[op](b);
    console.log(`- [X] ${op}`);
  } catch (e) {
    console.log(`- [ ] ${op}`);
  }
});

What are the steps to reproduce the behavior?

const pl = require('nodejs-polars')

const a = pl.Series([1, 1, 1]);
const b = pl.Series([2, 2, 2]);
a.add(b);

What is the actual behavior?

Uncaught Error
    at dtypeWrap (/opt/homebrew/lib/node_modules/nodejs-polars/bin/series/index.js:30:65)
    at Proxy.add (/opt/homebrew/lib/node_modules/nodejs-polars/bin/series/index.js:92:20) {
  code: 'DateExpected'
}

What is the expected behavior?

The above snippet should return pl.Series([3, 3, 3]).
