* begin adding sd.Card refactor * CSD logic shared between V1 and V2 * failing CRC7 implementation * passing tests * rename commands * implement waitToken * add status string method * no crc errors in status; closing the gap? * add config baud increase docs * remove some of API * still working on consolidation of init * fully comply * add prints * remove prints * remove unused API * add BlockDevice * implement Card interface * rename EraseBlocks to EraseSectors * add blkIdxer * working BlockDevice * delete rustref.go; add readme to sd * add sd/README.md * sd: backtrack on EraseSectors, stick to block nomenclature * remove remnants of sector size * fix examples/sd/main.go * add documentation, smoke test and fix a couple bugs

## `sd` package
|
|
|
|
File map:
|
|
* `blockdevice.go`: Contains logic for creating an `io.WriterAt` and `io.ReaderAt` with the `sd.BlockDevice` concrete type
|
|
from the `sd.Card` interface which is intrinsically a blocked reader and writer.
|
|
|
|
* `spicard.go`: Contains the `sd.SpiCard` driver for controlling an SD card over SPI using the most commonly available circuit boards.
|
|
|
|
* `responses.go`: Contains a currently unused SD response implementations as per the latest specification.
|
|
|
|
* `definitions.go`: Contains SD Card specification definitions such as the CSD and CID types as well as encoding/decoding logic, as well as CRC logic.
