Zstd compression level mapping

[MerinoSheep]

Bug description

Describe the bug
Documentation describes a 0-10 range which is not properly mapped to zstd's range of 1-22. The scaled value is saved to the PcapPlusPlus context but not the zstd compression parameter.

PcapPlusPlus/3rdParty/LightPcapNg/LightPcapNg/src/light_zstd_compression.c

Lines 60 to 61 in d1263a2

	context->compression_level = compression_level * 2; //Input is scale 0-10 but zstd goes 0 - 20!
	assert(!ZSTD_isError(ZSTD_CCtx_setParameter(context->cctx, ZSTD_c_compressionLevel, compression_level)));

Expected behavior
The scaling that gets applied to the context. For reference Technica-Engineering/LightPcapNG uses a slightly different calculation

//Input is scale 0-9 but zstd goes 1-22!
compression_level = (compression_level * 2) + 1;

Thank you @MerinoSheep for reporting this!
Do you have a pcapng in Zstd format that's not supported in PcapPlusPlus?
That way we can fix and test...
