Use with the cbor gem (or with cbor-pure, which is a
part of the cbor-diag gem) to
add a to_canonical_cbor method on objects.
Requires to_cbor to already be mostly canonical (as it is for the
above two CBOR implementations), just adds canonical ordering of maps
for completeness.
require 'cbor-canonical'
ex1 = {aa: 1, b: 2}
p CBOR.decode(ex1.to_cbor)
# {"aa"=>1, "b"=>2}
p CBOR.decode(ex1.to_canonical_cbor)
# {"b"=>2, "aa"=>1}
