signature for patricklodder

[patricklodder]

Reviewed and added my signature on top of the signed psbt from rnicoll in #27, because that was the only way I could get this to work.

Other signers can either sign this psbt and then we don't need to combine or sign rnicoll's and then we combine - it doesn't really matter which way.

script used:

dogecoin-cli walletprocesspsbt $(cat 2_processed_rnicoll.hex) true | jq -r .psbt > 2_processed_patricklodder.psbt
