Can't compile because crypto-mac = "^0.7" is missing

[EcoloSweet]

Apparently, the crypto-mac crate version 0.7 is now missing from crates.io and it prevents from compiling any project depending on poksho.

Do you have any idea on what to do?

At first I posted the issue on the zkgroup repo since i thought this repo is not maintained... But maybe we can find a workaround to update dependencies?

I'd love to help if there is any possibility to make a pull request here 😃

Ref to previous opened issue : signalapp/zkgroup#16

Here is my cargo command output :

I made this fork, updated dependencies and code so it works again : https://github.com/EcoloSweet/poksho

When code will be ready, I'll submit a pull request (if anyone here...)
