Skippable frames begin with a 4-byte magic number. There are 16 possible choices of magic number,
ranging from ZSTD_MAGIC_SKIPPABLE_START to ZSTD_MAGIC_SKIPPABLE_START+15.
As such, the parameter magicVariant controls the exact skippable frame magic number variant used, so
the magic number used will be ZSTD_MAGIC_SKIPPABLE_START + magicVariant.
