typeof "point_count_abbreviated" of a cluster

[onur-alp4]

Hi!

I recently started to get familiar with the package. Thanks for the awesome work so far!

I've noticed one unexpected behavior so far which is having the point_count_abbreviated property with two different types, number and string. It was unexpected because we already have point_count property which is always number and well the format of long number's point_count_abbreviated property should always be string anyhow. So I would suggest to have this point_count_abbreviated field as string by default.

What would be thoughts on this?
