-ARRAY: the classic command-line array, as AutoCAD lays it out (#2538)

Browse Source 
* Add -ARRAY, the classic command-line array, as AutoCAD lays it out

Rectangular arrays move the copy in row r and column c by (c * column distance, r * row
distance), asking for a distance only when there is more than one row or column; polar arrays
space n items 360/n apart around a full circle and fill/(n - 1) otherwise, turning the copies or
moving them with the group 10 point of the object selected last. The copies are separate
objects; the type asked defaults to the one used last.

* -ARRAY: refuse an unknown type and oversized arrays before making transforms

The JSON form errors on a type other than rectangular or polar, and checks MAXARRAY before the
copies' transforms are made; the command line bounds the columns by the rows (CodeRabbit).
