Lightning denotes transaction fee rate sats / 1000 weight units and sats / 1000 vbytes. Here we add support for creating BDK fee rate from lightning fee rate. We also move all FeeRate test to types.rs and rename as_sat_vb to as_sat_per_vb.

Description
Lightning denotes transaction fee rate sats / 1000 weight units and sats / 1000 vbytes.
Here we add support for creating BDK FeeRate from lightning fee rate. We also move all FeeRate tests to
types.rs and rename as_sat_vb to as_sat_per_vb.
Notes to the reviewers
Matt was concerned that we might round down value in fee calculation in such a way that a transaction may not be relayed because it is below Bitcoin Core's min relay fee (1 sat/vbyte). I don't think we need to worry about that because we round up(ceil) during fee calculation, we don't round down. I will love to hear what you think. Is there something I'm missing? @johncantrell97, I will appreciate your review on this one.
