DIY HSM #139

Not without tradeoffs, but Specter DIY could be turned into a DIY HSM module.

Similar to what coldcard does with https://ckbunker.com/ , users can create a policy allowing a USB connected Specter DIY to automatically sign PSBT matching a particular policy.

Such DIY HSM can also be part of a multisig.

My dream is to have coinjoin transactions signed automatically by a HWW: https://github.com/JoinMarket-Org/joinmarket-clientserver/issues/767#issuecomment-746474249
