Cardano Updates

Add a micro second timestamp in each payload for latency calculations.
If a message is too small to contain a timestamp no timestamp is
included and its tracked as "missing".
Use tdigest for calculating min, max, mean, median, p90, p95 and p99
stddev delay in ms.
Shows delat/latency stats, as speed and total speed.

Exit if cabal build fails.

Previous generator would filter out all duplicate tx's and hence
all downstream/outbound clients would have distinct mempools.

The new mempool implementation does not allow duplicates, so this
approach also allows detecting when duplicates are attempted to be
added to the mempool

Tracing improvements.

This fixes a bug where the same tx is enqueued multiple times for
submission into the mempool by the same peer.

spanl will silently drop trailing tx's if there is a gap
in the txs to acknowledge sequence. This may happen if acknowledging
tx's which some other peer has downloaded.

Fixed ghc-9.14 build

Use `main` branch rather than `merge_group`.
