Use multi-threaded compression and support more archive formats

[felipecruz91]

This PR:

• Adds support for more archive formats: zstd (.tar.zst) and bzip2 (.tar.bz2).
• The default archive format when exporting has changed from gzip (.tar.gz) to zstd (.tar.zst). Also, the compression implementation for gzip has changed to pigz (parallel implementation of gzip) which is faster.

I’ve run some benchmarks in GHA (2-cpu VM) with a volume that contains 4GB of Postgres data:

goos: linux
goarch: amd64
cpu: Intel(R) Xeon(R) CPU E5-2673 v4 @ 2.30GHz

Regarding time:

Nit: maybe set the default export name to be .tar.zst by default, as the performance gain is huge. LGTM
