"humility readmem" could be a little more usable about humility HOT 2 OPEN

I regularly trip over this, as you are aware from my complaining about it. :-)

FWIW openocd's monitor interface addresses the "bytes or words" problem by having separate commands. mdw is memory dump words that takes an address and (always) a number of words; mdb is memory dump bytes. Now if you want to specify a dump of an odd number of bytes but have it formatted as words...those commands are no help to you. But, humility readmem will also refuse this today.

One potential compromise between the convenience of having a large chunk of RAM print by default, and my desire to not have the tool perform more bus accesses than I was expecting, is to change the behavior based on whether Humility knows the area is normal RAM. Anything outside of normal RAM would be more stringent.

I for some reason thought this had been fixed, and used readmem to attempt to view a register, and Humility corrupted my debugging state by iterating over a bunch of FIFO registers. fwiw.
