Description

Using one of the alternate debounce algorithms requires a memory allocator.
ChibiOS allows you to disable said memory allocator.

This puts some compile-time checks to enforce that the allocator has been enabled -- during testing with it set to FALSE, the keyboard would run and function correctly from a visible standpoint, but no keypresses would register. The fun part was, if the slave side had a firmware that had an allocator enabled, the master would still report keypresses on the slave, but not itself!
