The length of ID in bytes is arbitrary but it can not exceed 63 bits (8 bytes).

+-------------------------
+- The speed for LZMA/LZMA2 compressing was increased by 3-10%,
+ and there are minor changes in compression ratio.
+- Some bugs were fixed.
+- The bug in 7-Zip 18.02-18.05 was fixed:
+ There was memory leak in multithreading xz decoder - XzDecMt_Decode(),
+ if xz stream contains only one block.
+- The changes for MSVS compiler makefiles:
+ - the makefiles now use "PLATFORM" macroname with values (x64, x86, arm64)
+ instead of "CPU" macroname with values (AMD64, ARM64).
+ - the makefiles by default now use static version of the run-time library.
