Merge with sf1/go-card?

[AndreKR]

There is a lot of overlap between this project and https://github.com/sf1/go-card.

I am currently using this project because I need GetStatusChange, but sf1/go-card has some nice things too, like the ISO Command APDU factory functions, the Reader struct with IsCardPresent() and WaitForCardPresent().

How do you feel about merging those features into ebfe/scard?

I'm the author of sf1/go-card and I certainly won't mind if anyone wants to have a go at this. The purpose of the ebfe/scard project seems to be to provide a direct wrapper for the winscard C API though, while sf1/go-card was meant to be a higher level interface from the beginning.

The implementations of the two projects are fundamentally different, especially on Linux/Unix where sf1/go-card connects directly to PCSC-Lite daemon instead of going through any C library.

I see sf1/go-card is archived these days, but I think there's merit in cgo-less on Linux talking to PCSC-Lite daemon directly. Thoughts on either converting this to pcsc-lite, possibly with a buildflag if we want to maintain support for the CGO version. For example could use the baked in cgo build flag as per https://pkg.go.dev/cmd/go#hdr-Build_constraints to to default to a cgo-less version if cgo isn't available (otherwise it would fail) and an explicit flag if someone wants cgo for other purposes but not cgo for pcsc-lite
