Some programs are not consistent across directories

[Davetbutler]

Describe the bug
The following programs do not run in the client_single_party_compute directory.

Mostly it is because the equivalent programs do not exist in the programs directory.

I suggest we remove them from the client_single_party directory so not to cause confusion (or we add the relevant programs in the programs directory.

"division_simple.py", "input_array.py", "modulo_simple.py", "nada_fn_composition.py", "power_simple.py", "reuse_simple_sub.py", "simple_sub.py", "single_addition.py", "tiny_secret_addition.py"
