zstd support about wsldl HOT 3 OPEN

I have released a new build that supports .tar.zst rootfs.
Please note that this may not be available in users version of WSL.

I will decide later whether to support zstd compression for vhd installs and backups.

from wsldl.

I'll keep this open as it's just partially solved, but personally I use native WSL export and redirecting that to Zstandard works perfectly, thus having no preference on zstd compression support by wsldl.

Code snippet in case anyone is interested:

wsl --shutdown
cd path\to\distro
# Make sure to use cmd as PowerShell pipe is known to be problematic
cmd /c "wsl --export Devuan - | zstd -T0 -o Devuan-$(Get-Date -UFormat "%Y%m%d").tar.zst"

from wsldl.

Ok, I understood.
I'll support it.
