v0.3.0

Many improvements and new functionality by @feelancer21 (thanks!)

new

• rules based on pending htlcs or next expiry
• new config options for inbound fees
• consideration of the local constraints during channel update (floor/cap the min_htlc_mat/max_htlc_msat)
• consideration of the commit fee in the balance calculation
• consideration of the unsettled balance (#111)
• add an onchain matcher to enforce policies based on current onchain fees
• circuitbreaker; control the node limits of a circuitbreaker instance dynamically
• logging: log RpcError and UpdateFailure (#83)
• logging: very very verbose option
• use onchain fee estimate of lnd instead of electrum, so no additional process needed (#2)

fixes

• matchers are now only called once
• imports cleaned up
