-	TODO: optimise this
-	write a full util for hexdump
-	how to optimise:
-	don't call print tens of thousands of times!
-	convert the numbers manually, and cache everything
-	in a BUFSIZ sized buffer, with everything properly
-	aligned. i worked out that i could fit 79 rows
-	in a 8KB buffer (1264 bytes of numbers represented
-	as strings in hex)
-	this depends on the OS, and would be calculated at
-	runtime.
-	then:
-	don't use printf. just write it to stdout (basically
-	a simple cat implementation)
