Made it feel like we're running out of bits in firmware for triggerDelay, but (a) rogue reads back the register correctly (b) Matt says he thinks we have 32-bits.

Addendum on May 18, 2021:  Matt found a bug in the Ben's trigger module (in cameralink gateway firmware, hsd, epix, kcu).  There is a delay 32-deep fifo where triggers go, and firmware was queueing every MHz slot and filling it up.  We couldn't set a large "user delay" (e.g. hsd "raw_start").
