- The splitting algorithm is redesigned to use random distribution of
subsplittings over channels.
- Splittings can include multiple subamounts within a channel.
- The single-channel splittings are implicitly activated once the
liquidity hints don't support payments of large size.
A penalty is added for split configurations which saturate a channel.
Saturation of channels is discouraged as we don't know the fees
beforehand. The penalty is accomplished via an exponential function that
kicks in when the subamount reaches about the total funds available
(this amount is controlled by the parameter EXHAUST_DECAY_FRACTION).
