[Bug]: unique_id fails when the number of cells is large relative to the element type

[kordejong]

Describe the bug

See title.

Expected behaviour

For out of range IDs no-data should be written

Steps to reproduce

array = lfr.create_array(100, 100, lfr.boolean_element_type, 1)
lfr.unique_id(array, np.int8)

Additional information

The code crashes in a debug build. Not sure what happens in a release build.
