[BUG] Module '"simple-datatables"' has no exported member 'convertJSON'

[shinokada]

• I have looked through the documentation to try to see if this behavior is documented.
• I have looked at the demos to see if one of them handles this, but none of them did.
• I have created a jsfiddle here: [INSERT LINK] that demonstrates the issue.

Describe the bug

According to the doc, you can import as the following:

import {
  DataTable,
  convertJSON
} from "simple-datatables"

But it has a type error: Module '"simple-datatables"' has no exported member 'convertJSON'.
