27e316571d Add a new type of flash chips, from Art Academy
It adds a new chip type, that works like regular 3DS saves. It
presumably is manufactured by Macronix as well.

Thank you for your help, @FerozElMejor on Discord and @Epicpkmn11

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)

This also limits the save blanking to the actual save area. This way

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.

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?

556c75c337 Fix many bugs by simplifying SPICARD init
* Fixed card reading (I didn't notice I broke it)
* Fixed cart swapping
* Still unsupported: CTR carts
* Still hangs if cart has no SPI flash (see WarioWare DIY)

The initialization code was simplified to only enable the SPICARD
interface, which assumes the *TRCARD interface has been initialized
beforehand.
To keep things simple, I just wrapped SPIWriteRead with SPICARD_Init and
SPICARD_deinit (which does the exact opposite)

2ceafc545b First viable(-ish) prototype
For some reason (messed up memory access?) the first two time I read the
status register, I get garbage.

Also:
* Reinserting card breaks SPI (everything reads 0xff
* No support for CTR carts for now
