lib: Add hexdump
Often during debugging session it's very interesting to see
what data we were dealing with. For example what we write or read
to/from memory or peripherals.
This change introduces functions that allow to dump binary
data with one simple function invocation like:
------------------->8----------------
print_hex_dump_bytes("", DUMP_PREFIX_OFFSET, buf, len);
------------------->8----------------
which gives us the following:
