953dd23665 taproot_output_script: first returned byte should be OP_1 (0x51) 
If we look at

  def IsPayToTaproot(script):
      return len(script) == 35 and script[0] == OP_1 and script[1] == 33 and script[2] >= 0 and script[2] <= 1

First byte is is checked for OP_1. OP_1 is 0x51

But the example code in this BIP returns  

`bytes([0x01, 0x21, output_pubkey[0] & 1]) + output_pubkey[1:]`

First byte 0x01, but it should be 0x51
