`read_len.finish()?` missing in some structs (fixed-length array structs?)

[rooooooooob]

shelley_tx_out = [address, amount: value]

does not seem to have it present at the end, causing an issue when this is in a type choice and two variants would overlap besides the length requirement e.g. the above with the following:

alonzo_tx_out = [
  address,
  amount : value,
  datum_hash
]
