Replace custom JSON error info format with tonic_types ErrorDetails. Add missing import for google/rpc/error_details.proto in lndkrpc.proto to enable proper decoding of ErrorInfo messages in grpcurl and other clients.
This commit introduces a parameter in the RPC to allow users to modify
the timeout when receiving an invoice from the offer creator.
Additionally, it adds a configuration parameter for the server to set
up a default value if no parameter is used.
The default timeout value is also decreased from 100 seconds to 20
seconds.
This commit expose two new endpoints to give users more control when paying
BOLT12 offers.
We use a hex serialization for the invoices. We should move to use a readable
from ldk and then hex serialize it in the future.
