get_available_scales: Available Boundary Scales for 'nomis' Table
Description
Retrieve available spatial scales for a given 'nomis' table id.
This is useful as each table only has data at a specific set of scales,
e.g. many census tables are available at MSOA and LSOA resolutions but not at Regional level.
Usage
get_available_scales(id)
Value
A tidy dataframe listing the geographical scales available for the 'nomis' table selected.
