headless: add --re-decrypt and --re-raw-base to the RE tool

--re-decrypt runs pspDecryptPRX() over a file and unpacks the KL4E/KL3E
stream behind it. This opens up flash0:/kd/resource/*.img, the images the
Media Engine actually runs: they are ordinary tagged containers (tag
862648D1, which PrxDecrypter already has a key for) with the ~PSP
signature blanked, so the normal module loader never touches them.

--re-raw-base analyzes --re-module as a flat code image at a given
address rather than as a PRX. The decrypted ME images are raw MIPS with
no ELF around them; the address they were linked for is recoverable from
their own jal targets (0x08300000 for meimg.img).

Also makes PrxDecrypter.h self-contained - PSP_Header is built from _le
types, so it needs Common/Swap.h rather than relying on the includer.
