RESEARCH: CoinKite Bunker on the RaspiBlitz

[openoms]

ckbunker.com is great to have for people having a ColdCard MK3 already.

It is ideal to run on this reasonably secure always-on linux server we already use.

Made it work quite easily, documented here: https://github.com/openoms/bitcoin-tutorials/blob/master/ckbunker_on_blitz.md

Could be a new optional feature in the next release.

This feature got a big boost with JoinMarket developments to allow external signing: JoinMarket-Org/joinmarket-clientserver#663 (comment)

Funding with a PSBT is already available in LND (using bitcoin-cli): https://github.com/lightningnetwork/lnd/blob/master/docs/psbt.md or with Balance of Satoshis https://github.com/alexbosworth/balanceofsatoshis:
