Add support for Gatekeeper Guard

[TYRONEMICHAEL]

Hey @MarkSackerberg ,

Thanks for all the work on this. I am creating a PR that adds support for the Gatekeeper Guard. Let me know if you need anything from me?

Someone is attempting to deploy a commit to a Personal Account owned by @MarkSackerberg on Vercel.

@MarkSackerberg first needs to authorize it.

Hey @TYRONEMICHAEL ,
thank you for the PR!
I've given it a devnet testrun with this gatekeeper config:

 "gatekeeper": {
    "gatekeeperNetwork": "ignREusXmGrscGNUesoU9mxfds9AiYTezUKex2PsZV6",
    "expireOnUse": false
}

Unfortunately the mint fails with:
Program logged: "AnchorError { error_name: "GatewayTokenInvalid", error_code_number: 6023, error_msg: "Gateway token is not valid", error_origin: Some(Source(Source { filename: "program/src/guards/gatekeeper.rs", line: 63 })), compared_values: None }, Candy Guard Botting is taxed at 10000000 lamports"

I assume this is not expected behaviour?
Which config did you use for testing?

Hey @MarkSackerberg,

I will look into this today. The only difference I see immediately is that my config was set to "expireOnUse": true. Did you go through the captcha flow before signing the mint TX? i.e did you have to sign twice, once for the GT token, and second for the Mint?

[MarkSackerberg]

No, I just had to sign the mint TX.

[TYRONEMICHAEL]

Strange. That would explain the error then. You need a Gateway Token in order to mint. So it must be an issue in [here]( https://github.com/MarkSackerberg/umi-cmv3-ui-inofficial/pull/15/files#diff-9fcb2da6f2ba63e8e9702d369f78270fc31628c23ebaf35c5700f5c59da711a9R370). Do you mind sending me the address of the wallet that you used to test and maybe the CM config you used? I assume it was on devnet?
