firmware: Add the support for ZSTD-compressed firmware files
As the growing demand on ZSTD compressions, there have been requests for the support of ZSTD-compressed firmware files, so here it is: this patch extends the firmware loader code to allow loading ZSTD files. The implementation is fairly straightforward, it just adds a ZSTD decompression routine for the file expander. (And the code is even simpler than XZ thanks to the ZSTD API that gives the original decompressed size from the header.)
