properties type definition seems incomplete

[arasmussen]

In SimplePublicObjectInputForCreate or SimplePublicObjectInput, properties is defined as:

    'properties': {
        [key: string]: string;
    };

This seems incompatible with HubSpot's properties, which can be dates, booleans, numbers, or null...

I can definitely convert:

• number → number.toString()
• boolean → String(boolean)
• null → ''
• date → date.toISOString()

But it seems like @hubspot/api-client should accept all primitives types and do the conversion on its side if you truly require it...
