C library

I think it is important that dnadesign is usable with C. This is primarily so it can be embedded into a python package for use with AI systems. Systems where performance is really important can still be C - but it would be very nice to have basic functions for unique features to be callable from Python!

This should start fairly simple, but expand from there.

This will probably be with cffi, because of the support for using specifically the C ABI.

https://github.com/go-python/gopy this looks very promising

looks like it has a difficult time with channels and multiple returns:

ignoring python incompatible method: bio.func (*github.com/koeng101/dnadesign/lib/bio.Parser[github.com/koeng101/dnadesign/lib/bio/fasta.Record, github.com/koeng101/dnadesign/lib/bio/fasta.Header]).ParseToChannel(ctx context.Context, channel chan<- github.com/koeng101/dnadesign/lib/bio/fasta.Record, keepChannelOpen bool) error: func(ctx context.Context, channel chan<- github.com/koeng101/dnadesign/lib/bio/fasta.Record, keepChannelOpen bool) error: gopy: type is channel type
ignoring python incompatible method: bio.func (*github.com/koeng101/dnadesign/lib/bio.Parser[github.com/koeng101/dnadesign/lib/bio/fastq.Read, github.com/koeng101/dnadesign/lib/bio/fastq.Header]).ParseWithHeader() ([]github.com/koeng101/dnadesign/lib/bio/fastq.Read, github.com/koeng101/dnadesign/lib/bio/fastq.Header, error): func() ([]github.com/koeng101/dnadesign/lib/bio/fastq.Read, github.com/koeng101/dnadesign/lib/bio/fastq.Header, error): gopy: too many results to return: func() ([]github.com/koeng101/dnadesign/lib/bio/fastq.Read, github.com/koeng101/dnadesign/lib/bio/fastq.Header, error)

I think the play will be to write a completely separate package that just imports everything and makes nicely compatible C functions that can alternatively be compiled with vanilla -buildmode=c-shared, or with gopy.
