[requires fork] Elements should have a jet to access input asset ID for reissuances #327
Description
Elements has some annying logic for reissuances in which you are required to spend a confidential output containing a reissuance token, but you must reveal the blinding factor, in order to do a reissuance.
This is crazy but requires a hardfork to fix.
Meanwhile, for contracts to assert on the input type of a reissuance token, they need to reimplement the unblinding logic in Simplicity. (Or hack the crypto by doing ugly/inflexible/poorly-supported-by-wallets things like enforcing that an output asset have exactly the same commitment as an input asset.)
Anyway we ought to have a jet to do this work. Unsure where the best place to post "jet wishlist" issues is.
