Comment:
error `github.com/anatol/booster/generator/image.go:55:16: undefined: lz4.NewWriterLegacy` comes from the fact that pierrec/lz4 dependency that you pull does not have `lz4.NewWriterLegacy` struct. 

Upstream has it since March 2021 https://github.com/pierrec/lz4/blob/master/writer_legacy.go  And if you use go mod build system it will pick the correct dependency version for you.

I am not familiar with go build system at Void but my guess is that you do not use built-in go modules resolver and instead manage dependencies manually. In this case that dependency needs to be adjusted to match https://github.com/anatol/booster/blob/0.7/generator/go.sum.
