Teensy 4.1 core updated for C++20

Frank 3605d91f39 optimized delayNanoseconds shifting both sides by 16 bit gives pretty good accuracy with fast code: movw r3, #9155 ldr r2, .L2 mul r0, r3, r0 lsrs r0, r0, #1 umull r3, r0, r2, r0 lsrs r0, r0, #8 .L2: .word 144122641 with 984 MHz it allows nsec to be max ~143000 max which is plenty		преди 6 години
