Trapping asserts

-> https://nullprogram.com/blog/2022/06/26/ by Chris Wellons (Skeeto)

Called SAL_ASSERT for now, because of some unresolved macro conflicts
(possibly due to the SFML interface headers also including <cassert>):
despite redefining (#undef + #define) here, an assert(0) still did the
same old standard print + abort thing! :-o
