Compress releases with zstd

[tom-neara]

zstd --ultra -22 generates smaller files than xz and decompresses an order of magnitude faster, is there any reason not to use zstd? I re-compress releases with zstd for my team to save them time when extracting, but it would be nice if the releases where natively compressed using zstd.
