Fix mempool.get_info, testmempoolaccept and outpoint.subscribe with the Palladium daemon

Browse Source 
- mempool.get_info: the daemon has no incrementalrelayfee in getmempoolinfo,
  read incrementalfee from getnetworkinfo
- testmempoolaccept: the daemon does not report wtxid
- outpoint.subscribe: refuse the subscription (Coin.DAEMON_HAS_TXO_SPENDER_INDEX)
  instead of closing the session at the next block, when the daemon errors

Coin abstraction: `lib/coins.py` defines `Coin` and the `Palladium`, `PalladiumTestnet`, `PalladiumRegtest` subclasses. A coin class selects behavior through class attributes: `DESERIALIZER` (block/tx format, in `lib/tx.py`, only the segwit one remains), `DAEMON`, `BLOCK_PROCESSOR`, `SESSIONCLS`, address verbytes, `GENESIS_HASH`, `REORG_LIMIT`, `RPC_PORT`, `PEERS`, header handling, etc. Coins are discovered by walking `Coin` subclasses (`lookup_coin_class` matches `NAME` + `NET`; `COIN` defaults to `Palladium`). Concrete classes must define `TX_COUNT`, `TX_COUNT_HEIGHT`, `TX_PER_BLOCK` (used only for sync ETAs) or lookup raises.
Daemon: Palladium Core has segwit and taproot (BIP341/342, mainnet height 405000; the server is script-type agnostic, indexing by script hash) and bech32/bech32m addresses, but no `getindexinfo`, `txospenderindex` or `submitpackage` RPCs. So `MIN_REQUIRED_DAEMON_VERSION`/`REQUIRED_DAEMON_INDEXES` (see `Coin`) are unset, and `blockchain.outpoint.subscribe` / `blockchain.transaction.broadcast_package` return a daemon error to clients. The daemon needs `txindex=1`.

So `MIN_REQUIRED_DAEMON_VERSION`/`REQUIRED_DAEMON_INDEXES` (see `Coin`) are unset, and `blockchain.outpoint.subscribe` is refused with an explicit error (`Coin.DAEMON_HAS_TXO_SPENDER_INDEX = False`: otherwise the subscription is accepted and the daemon error at the next block closes the session) while `blockchain.transaction.broadcast_package` returns the daemon error to clients. The daemon needs `txindex=1`.
DB schema changed in 2.0 with no migration; changing on-disk format requires a full resync.
