Support rendering TableEditorView from csv (Step 2 of issue #1758)

[robyngit]

• Add a robust, tiny, popular csv parser PapaParse
• Support initializing TableEditorView with a csv string, e.g.

const myTable = new TableEditorView({
  csv: `ID,Fruit,Number
    1,Apple,123456
    2,Orange,234567
    3,Watermelon,345678`,
});
