7af76b91bb Detect save size by the last byte of JEDEC id, if possible 
This is my second attempt to resolve #553

Props to @wwylele for pointing out that the last byte of the JEDEC ID is
just the exponent of the size (base 2)

9f52deedad Card-2 saves: Detect save size from ExHeader 
This also limits the save blanking to the actual save area. This way
every byte of the cart can be read again.

f2e52bd1c7 Initial support for CARD2 read 
Can I get card2 writing to work?

Am I _that_ good?

Will I break by copy of X?

I won't know until I try!

25a22d30d0 gamecart: Added a gamecart_id.bin file. 
This contains the 4-byte chip ID.

d63db4bc6d gamecart: Use the chip ID's TWL flag to check if we should do TWL secure area init. 
It's possible to flash a TWL-enhanced ROM image to an NTR dev cart.
This cart would function properly as a Nintendo DS game, but might
have issues on a DSi or 3DS.

GodMode9 couldn't dump this type of cartridge before because the ROM
header indicates TWL, but the cartridge doesn't understand the 0x3D
TWL secure area init command, so key exchange failed.

cadd21508f gamecart: Use the chip ID to determine the ROM size. 
Some development carts have an incorrect ROM header, but the cart ID
is always correct, so prefer the chip ID. If the chip ID is invalid
(unlikely), then fall back to the ROM header.

fa741b265b Write support for NTR saves 
Why does this work? We are writing flash memories without erasing them,
and writing pages without regard to alignment. Yet it works?

f60a4c1f63 Add a vfile to show the JEDEC id for the inserted cart 
This is meant to replace the Prompt I was using previously.
Fun fact: WarioWare DIY seems to have *something* on the SPI bus, as it
returns an ID of 0x000001 consistently. Or am I just glitching the
parallel flash? Or did I get a fake?
