Limited data viewing on frontend gui data explorer

1. if there exists more than 200 measurements in a bucket you can only view the first 200.
- if you search in the filter box you can view measurements that exist in the bucket but aren't shown initially
2. if there exists more than 100 buckets you can only view the first 100 buckets.
- buckets are confirmed to exists via bucket creation responses from API and ability to query data from the bucket from API
- you cannot view these additional buckets by searching in the filter. its as if they don't exit from the data explorer's perspective

__Expected behavior:__
ability to view all buckets and measurements by continuously scrolling or searching.

__Actual behavior:__
cannot view buckets over 100, does not show more than 200 measurements at a time
