SPZ v2

[azadbal]

Hi there, following up from a request on Discord.

Just wanted to ping you regarding the fact that we've recently updated SPZ v2 to include a major improvement to maximize the accuracy of the quantization of Gaussian rotations (you can follow the PR).

We recommend updating your SPZ dependency to the latest version so that any SPZ file written with v3 can be properly read.

Thank you!
