If bitcoin core's txospenderindex is enabled and sync, we'll automatically use it to find transactions that spent our channels.
On startup, eclair will check that both txindex and txospenderindex are enabled and synced, and will stop if they're not. Block scanning code used to find spending transactions is removed, we just use the txospenderindex now.

done in cd31b14. Eclair won't start if the index is not enabled and synced. |

Eclair now requires that bitcoin core's
txospenderindex(added in version 31.0) is available and synced, and will fail to start if it is not.Our Watcher will use the txospenderindex` to find spending transactions instead of scanning blocks (which was both expensive and limited as we would only scan a small number of blocks into the past).
Deployment note:
You must enable the new index on bitcoin core with
txospenderindex=1and wait until it is synchronised before you start eclair. Syncing the index from scratch will take a few hours, during which bitcoin core is usable (indexes are independent) but make be slower to respond.You can also copy the index from another node (that is running the same version), just copy the entire
.bitcoin/indexes/txospenderindexdirectory.The index requires an additional 88Gb as of block 944339.
