The outputs of txref are different from examples in bip136

[KimiWu123]

In bip136, here are examples,
Genesis Coinbase Transaction (Transaction #0 of Block #0): tx1:rqqq-qqqq-qmhu-qhp
Transaction #2205 of Block #466793: tx1:rjk0-uqay-zsrw-hqe

I used your tool to en/decode these txref but I got errors or inconsistent result. Here is my command to encode,

$ ./txref  -e -m 3 -b 466793 -p 2205
// result: encodedTxref: tx1:rjk0-u5ng-4jsf-mc
$ ./txref  -e -m 3 -b 0 -p 0
// result: encodedTxref: tx1:rqqq-qqqq-qmhu-qk

and if I decode

tx1:rjk0-uqay-zsrw-hqe

I got error,

err: Decoded data is not 8 or 10 characters long

Any idea? Thanks.
