Add option to set allowance during mint

[hard-nett]

Multi-contract systems involving snip20's could benefit from having an optional field in the mint function to set an allowance for another wallet address.

what's the use case here? the minter is usually not the recipient of the funds, and if it is you can send a multi-message tx.

Theres a few:

• non-custodial loans: An escrow contract can be granted allowance when new tokens are minted to automatically send itself the snip20 as collateral
• distribution-gauges: create supply managed by results of custom gauges.
• custom derivative policies: enforce various requirements on snip20 derivatives, similar to gauges.
• game-fi: allow game creators to implement custom strategies while making use of snip20
