support for setCollection during mint

[nftechie]

Hello! We hit an issue today during a mint, and realized we needed to set the collection ID during mint.

Here is an example transaction that was bot penaltied: https://explorer.solana.com/tx/2zP6tEw9vzGxGkPSDTyLKEzJieuP57LvzN8ddDbhm2cxaQR3PReqmA8pKLgYQYQP9sBbbABGFnZYqQuSMm6USjBV

You can see the error at the bottom of that tx:

Missing set collection during mint IX for Candy Machine with collection set, Candy Machine Botting is taxed at 10000000 lamports

In early March, it looks like Metaplex added a setCollection method: metaplex-foundation/metaplex@58679aa

Is there any chance you could add support for this?

That above metaplex link I sent was for setCollection, but it looks like there's instruction we'd need to set specifically during mint. Here's an example metaplex uses in their typescript client: https://github.com/metaplex-foundation/metaplex/blob/ffd3372a0c5e1700ebc70f8b8835083685eb65ca/js/packages/cli/src/commands/mint.ts#L371
