processParams not converting extent to string

[benstoltz]

Describe the bug

addItem and updateItem both expect extent to be a flattened string instead of a bbox ( 1, 2, 3, 4 vs [[1, 2], [3, 4]] ). Apparently around two years ago we made a change to processParams ( #779 ) for catalog to allow array of arrays through. At that time it was decided to do that for all the cases so as to not make an explicit reference to a property. Unfortunately that has broken extent. What ends up happening is in the actual request the bbox is split into two different extent params, the create/update call succeeds, however the item ends up with an extent which is simply an empty array.

@benstoltz please implement the conversion from number[][] to string in the createItem and updateItem functions, and leave the processParams function as-is
