zstd 1.4.8

This release updates the upstream zstd version to 1.4.8 (#93)

zstd 1.4.5 - wrapper patches 2

The semantic versioning of this release is a bit particular since it only includes changes in the Go wrapper without any changes from the upstream C repository (https://github.com/facebook/zstd/releases).

Changes:

• Pass pointers to C as unsafe.Pointer, not uintptr (memory corruption) @evanj (#91)
• Add go.mod file @Viq111 (#94)
• [circleci] Fix 32 bits builds @Viq111 (#92)

This is a recommended version as it fixes a potential memory corruption bug when the system is under-pressure (memory and/or lots of threads) which forces the Go runtime to move the stack around.

edit: This version went back to pre-release as it contains a bug when using a Writer object from another package (see #97)

zstd 1.4.5 - wrapper patches

The semantic versioning of this release is a bit particular since it only includes changes in the Go wrapper without any changes from the upstream C repository (https://github.com/facebook/zstd/releases).

New APIs:

• Ctx.Compress, Ctx.CompressLevel & Ctx.Decompress were added thanks to @merlimat . This new API is useful for compressing/decompressing a lot of small payloads with better performance. (#83)
• Writer.Flush() was added thanks to @delthas (#86).

CI related PR:

• Run CI against Go version 1.14 & 1.15 @Viq111 (#87)
