batchUstVerifier and qvtVerifier on the MACI contract are inaccessible externally

[yuetloo]

Hi,

Is it possible to make these accessible publicly? It'll be useful for debugging purposes. These can still be accessed today using getStorageAt, making them public will make it easier to get the values.

   // Verifier Contracts
    SnarkVerifier internal batchUstVerifier;
    SnarkVerifier internal qvtVerifier;

I'll investigate if we can support this for v1.0 as well

I'm closing this as it applies to 0.x, feel free to re open if there is a similar need in the v1.x code.
