missing support for some error codes returned by the mint

[elnosh]

there are some error codes from the spec that are missing. The ones I noticed:

• outputs already signed (10002)
• token could not be verified (10003)
• amount outside of limit range (11006)

Nutshell returns all these errors but using codes different from the spec.

Specifically what is the text of the errors for each one you noticed?

[elnosh]

• outputs already signed (10002)
• token could not be verified (10003)
• amount outside of limit range (11006)

• "outputs have already been signed before."
• "could not verify proofs."
• "Maximum mint amount is {} sat."

For the first two it uses TransactionError it looks like which sets the code to 11000.

Just ran into this as well:

nutshell/cashu/mint/verification.py

Line 144 in 2f19485

raise TransactionError("outputs have already been signed before.")
