BIP 69 proposed a deterministic way to sort transaction inputs and
outputs with the idea of enhancing privacy. It was later discovered
there was no such enhancement but rather a decrement in privacy due to
this sorting.
To avoid the promotion of bad practices, the
TxOrdering::Bip69Lexicographic variant which implemented this BIP for
BDK is removed with this change.
Notice that you can still produce a BIP 69 compliant transaction
defining order functions for TxOrdering::Custom.
