Add support for SDSC (≤2GiB) SD cards #224

Closed midnightveil closed 1 week ago

Tested on on a 2GiB SDSC Card, matches with mmc-utils on Linux.

Client read/write data is correct!

In theory, should also work on SDXC (32GiB -> 2TiB) and SDUC (> 2TiB), though we don't have cards to test.

Waiting on #206 to merge first. Part of #187.
