Update NPM package to use Ag Grid 31.1.0

[maxhille]

This change updates the NPM package to use AG Grid 31.1.x

Notable proposed changes:

• The custom element wrapper code got simplified due to simplification in AG Grid's API
• AG Grid changed how internal modules are set up and also integrated big new features (like embedded charts) we we do not yet support. So it makes sense to no longer include the packaged versions but the modules to we can only import the needed parts.
• Since users upgrading to this package version have to change their embedding code, the version bump is major.

Also Closes #3

Ag-grid added data type inferring https://www.ag-grid.com/javascript-data-grid/cell-data-types/ this could simplify a few things in the future. But I wonder if we need to disable it for now to make sure that our formatting code still works.

Are you sure this is new (after v29)?
