Utilities for working with ascii85 encoding.

This module is browser compatible.

Specifying a standard and delimiter

By default, all functions are using the most popular Adobe version of ascii85 and not adding any delimiter. However, there are three more standards supported - btoa (different delimiter and additional compression of 4 bytes equal to 32), Z85 and RFC 1924. It's possible to use a different encoding by specifying it in options object as a second parameter.

Similarly, it's possible to make encode add a delimiter (<~ and ~> for Adobe, xbtoa Begin and xbtoa End with newlines between the delimiters and encoded data for btoa. Checksums for btoa are not supported. Delimiters are not supported by other encodings.)
