BlackMark f9b86393e1 build: emit a raw .bin beside the HEX for every loader image ...

The host tool takes either form — load_image() parses Intel HEX by extension
and treats anything else as raw bytes — but the build emitted only the HEX, so
the raw path had no artifact behind it. The reloc and update tests each shell
out to objcopy at runtime to produce one for themselves.

add_hex_output becomes add_image_outputs and emits both forms. The .bin is
byte-identical to the plain `objcopy -O binary` those tests generate (-R .eeprom
strips nothing the loaders carry), and decodes equal to the HEX payload — 504 B
at 0x7e00 either way for pureboot. Sizes come out at the flash sizes exactly
(504/510/836/526), so nothing stretches to the .data load address.
