changed the title
Previously, we would cast `FeeRate::to_sat_per_kwu` to `u32`, which however might result in `u32::max_value` being used if our fee estimation source delivers huge bogus data. Here, we make sure to use the fallback rate if we would do so otherwise.

Based on #426.Previously, we would cast
FeeRate::to_sat_per_kwutou32, which however might result inu32::max_valuebeing used if our fee estimation source delivers huge bogus data. Here, we make sure to use the fallback rate if we would do so otherwise.We also make sure our post-estimation adjustments could never underflow.
Both of these changes aren't super critical but make the code a bit more robust.
