+/*! ZSTD_compressSequencesAndLiterals() :
+ * This is a variant of ZSTD_compressSequences() which,
+ * instead of receiving (src,srcSize) as input parameter, receives (literals,litSize),
+ * aka all literals already extracted and grouped into a single continuous buffer.
+ * This can be useful if the process generating the sequences also happens to generate the buffer of literals,
+ * thus skipping an extraction + caching stage.
+ * To be valid, `litSize` must be equal to the sum of all @.litLength fields in @inSeqs.
+ * @return : final compressed size, or a ZSTD error code.
