Impossible to install v0.3.0 because of zstd

[dunglas]

Expected behavior

It should be possible to install the latest version.

Actual behavior

PR #385 conflicts with other libs depending on github.com/DataDog/zstd. In my project, zstd is a transient dependency of many other open source dependencies, and all the other ones are using github.com/DataDog/zstd. This leads to an installation error:

../../go/pkg/mod/github.com/apache/[email protected]/pulsar/internal/compression/zstd_cgo.go:27:2: case-insensitive import collision: "github.com/datadog/zstd" and "github.com/DataDog/zstd"

Downgrading to v0.2.0 fixes the issue on the short term.

Steps to reproduce

go get -u

should wait for golang/go#26904 to allow replace like

replace github.com/DataDog/zstd v1.4.6-0.20200617134701-89f69fb7df32 => github.com/datadog/zstd v1.4.6-0.20200617134701-89f69fb7df32

I have same issue, from pkg.go.dev statistics, DataDog/zstd is used much more often than datadog/zstd

A temporary solution, if you don't need to use zstd related functions, you can simply replace this file and remove the code related to zstd, for example https://github.com/streamnative/pulsar-beat-output/blob/master/zstd_cgo.go

cp zstd_cgo.go /your-file-path/go/pkg/mod/github.com/apache/[email protected]/pulsar/internal/compression/zstd_cgo.go

Anyway, data dog had added go.mod file to their library, so I believe, we can update dependency here too
