SDIO mode support for SD cards

[Cursor-S]

Any plan for supporting SDIO mode for SD cards? That's useful in improving the speed while r/w files in cards.

Besides, thank you to build such a great project 🥰

@Cursor-S Thank you for using Kaluma. Now we don't have a plan for SDIO based SD Card module because RP2040 does not have SDIO hardware. We can make java script project for it using current APIs (PIO and block device).
