v0.3.0

Logging support has been added to flashcart_core, and therefore to ntrboot_flasher!

Logs should be generated at /ntrboot/ntrboot.log, and should contain cart dependent information like the hardware revision for Kk2i and R4i Gold 3DS, or flashchip ID for DSTT. This should make some forms of debugging easier, now that the framework is in place.

Meanwhile, a few more DSTT chips have been given support.

Cheers!
