fix: convolution test deadcode

[mizar]

This pull request makes a minor change to the test module in src/convolution.rs, specifically by removing an unused or unnecessary macro invocation. No functional changes to the code logic are introduced.

• Removed the modulus!(M1, M2, M3); macro call from the test module in src/convolution.rs, likely because it was redundant or not needed.

OK. This code seems to be dead ever since I wrote #45.
