Added optional read/prog/erase delays to testbd

Browse Source 
These have no real purpose other than slowing down the simulation
for inspection/fun.

Note this did reveal an issue in pretty_asserts.py which was clobbering
feature macros. Added explicit, and maybe a bit hacky, #undef _FEATURE_H
to avoid this.
