Support Zstandard as compression algorithm

[gangsthub]

Describe the feature

Zstandard is a fast compression algorithm, providing high compression ratios. It also offers a special mode for small data, called dictionary compression. The reference library offers a very wide range of speed / compression trade-off, and is backed by an extremely fast decoder

Currently, the options to pre-compile the public assets only allow gzip "and/or" Brotli: https://nitrojs.dev/config#compresspublicassets

Potentially, zstd could provide smaller files, faster (in some scenarios –yet to be investigated).
