zip-rs no longer maintained

[antiochp]

The library we use for zip/unzip functionality is currently unmaintained.

Unfortunately, due to a lack of time and loss of interest, this project will no longer be actively maintained.

We should probably find a suitable replacement (for as long as we still rely on zip file format).

How about https://github.com/alexcrichton/bzip2-rs?

[eupn]

What about to get rid of archive files (such as .zip) and send contents of txhashset as a compressed blob? This also should be more robust as it will less rely on filesystem operations (issues like CVE-2019-1995)

We should probably find a suitable replacement (for as long as we still rely on zip file format).

Will this help? https://github.com/fpgaminer/rust-lzma
