offline encryption/decryption using LUKS formats (library)

 luksy implements encryption and decryption using LUKSv1 and LUKSv2
 formats. Think of it as a clunkier cousin of gzip/bzip2/xz that doesn't
 actually produce smaller output than input, but it encrypts, and that's
 nice.
 .
 The main goal is to be able to encrypt/decrypt without the Linux device
 mapper. Duplicating functions of cryptsetup that it can perform without
 accessing the Linux device mapper is not a priority.
