OpenOCD may return hex values from mem2array or mrw, so allow those.
mem2array output:
0 0xb8 1 0xba 2 0xc 3 0x0 4 0xb8 5 0xba
This might depend on the particular adapter driver being used but
parsing either is more robust. The problem was observed with OpenOCD
0.12.0 and cmsis-dap.

`mrw` requires that mem_helper.tcl is sourced, whereas read_memory can be used without any config.

These are a couple of small fixes for things that were preventing humility working with OpenOCD (in my setup at least). I'm not certain of the internals of OpenOCD that would cause differences between what was previously tested, maybe adapters handle their own formatting?
