SomberNight f337b4782d lnwatcher: keep watching sweep TXOs that are dust due to high fees ...

- if fee estimates are high atm, some outputs are not worth to sweep
- however, fee estimates might be only-temporarily very high
  - previously in such a case lnwatcher would just discard outputs as dust,
    and mark the channel REDEEMED (and hence never watch it or try again)
  - now, instead, if the outputs would not be dust if fee estimates were lower,
    lnwatcher will keep watching the channel
    - and if estimates go down, lnwatcher will sweep them then
- relatedly, previously txbatcher.is_dust() used allow_fallback_to_static_rates=True,
    and it erroneously almost always fell back to the static rates (150 s/b) during
	startup (race: lnwatcher was faster than the network managed to get estimates)
	- now, instead, txbatcher.is_dust() does not fallback to static rates,
	  and the callers are supposed to handle NoDynamicFeeEstimates.
	  - I think this makes much more sense. The previous meaning of "is_dust"
	    with the fallback was weird. Now it means: "is dust at current feerates".
