Thanks for finding this bug. This is similar to a previously fixed bug,
where OID components would be encoded incorrectly.

Please factor out the code you added into a decode_oid_component
function (to go with encode_oid_component). There's a web link above
encode_oid_component with documentation on the encoding.
