Add Bolt12CreationError error type to ChannelManager
Browse files Browse the repository at this point in the history 
Introduced the Bolt12CreationError error type for bolt12
errors that occur outside the builder. This error type is
used in the ChannelManger functions. I moved, DuplicatePayment,
and InsufficientLiquidity out of Bolt12SemanticsErrors into
the new error type as well.

Additionally, I updated the code to replace occurrences
where we replaced Bolt12SemanticsErrors with the new
Bolt12CreationError type throughout the relevant files.
