This PR is based on #12 and will fix #13.

The generic implementation doesn't require that it's safe to perform unaligned word-sized loads, but has a poor performance.

Also, I wonder whether the related code can be rewritten to not use unaligned memory accesses?

Go 1.16 makes go.mod mandatory:
https://blog.golang.org/go116-module-changes

This caused two errors:

(1) go build failed:

  go: cannot find main module, but found .git/config in /home/jakob/go/src/github.com/jacobsa/crypto
  	to create a module there, run:
  	go mod init

Fixed by adding go.mod & go.sum.

(2) tests failed:

  subkey.go:47:
  panic: Finding package: no required module provides package github.com/jacobsa/crypto/testing/cases; to add it:
  	go get github.com/jacobsa/crypto/testing/cases

Fixed by adding testing/cases/cases.go.

Hi @paralin,

@piggynl I'm wondering if it might be good to fork this & maintain it as a different import path if the author doesn't merge.

Sure! Do you prefer maintain the fork at aperturerobotics/jacobsa-crypto or piggynl/jacobsa-crypto? I have some ideas on using QEMU on GitHub Action to test packages for different architectures.

@piggynl Since that org already has a number of forked repos under maintenance, I'm happy to put it there.

Do we keep the name jacobsa-crypto? I can change the go.mod there to match.

OK, changed the go.mod & invited you as a maintainer.
