Rusty Russell 7bde0ead4d connectd: allow out-of-bounds fees unless they're actually getting *worse*.
Pointed out by @fiatjaf, and indeed it happened to me as well; a peer with
a high feerate reconnects and sends a similar (but now ludicrous) feerate,
and we get upset:

```
$ lightning-cli listpeers 039c73f53daad1050a6a72afb5353a2152f3152ee17168cd0ab28c2cb3e0050e36
{
   "peers": [
      {
         "id": "039c73f53daad1050a6a72afb5353a2152f3152ee17168cd0ab28c2cb3e0050e36",
         "connected": false,
         "channels": [
            {
               "state": "CHANNELD_NORMAL",
               "scratch_txid": "d796aa9c44920cc7169cdb61e36437bf180cedaec44103a69591ce2baac9b1d9",
               "last_tx_fee": "14329000msat",
               "last_tx_fee_msat": "14329000msat",
               "feerate": {
                  "perkw": 19791,
                  "perkb": 79164
               },
```

Then in the logs:
```
