[Enhancement] Make lookup() method accept named params

[prescience-data]

Currently, the main lookup method is configured to accept a series of params:

async lookup(ip?: string, selectField?: string, fields?: string[])

The issue is if you are wanting to set only one of these, you need to pass undefined to the preceding params.

A common pattern to help solve this scenario would be:

export interface LookupParams {
  ip?: string
  selectField?: string
  fields?: string[]
}

// ... main class
{
  async lookup({ ip, selectField, fields }: LookupParams = {}) {
   // ... lookup logic
  }
}

Naturally, changing the shape of the method signature is a tricky undertaking, so potentially you could run a type check on the first param and keep the existing ones to allow backward compatibility?

@thomasconner thoughts?

Yes this would be much better. I think a major version bump would be better to help people opt in rather then trying to maintain backwards compatibility. I can work on making this change this week.
