`show_values` not returning content with >400 rows

[mjwestgate]

With changes to the ALA APIs, we are now limited to 400 rows, even for large datasets. For example, the GRIIS list stored by ALA here has 2984 rows, but:

search_all(lists, "dr17242") |> show_values() |> nrow()
• Showing values for 'dr17242'.
[1] 400

To solve this, we can either add a higher max value to the API call, or paginate.

Sub-issue: should the df arg in show_values be labelled .data for consistency with other functions?

Note: atlas_GET contains pagination code that may duplicate atlas_paginate; check for efficiencies

As of v 1.5.1 this appears fixed, albeit with optional limitation of number of rows via limit argument
