Snapshot after the 'c' command efficiency bugfix. Also removed some redundant code and the vectorized encoder no longer needs to change the rounding mode.

initial release

There's a known efficiency bug in this version: the 'c' command may generates files which are too large if the input file size is >65535 bytes. This was caused by an overflow in the code which scaled the input frequencies to 16-bits in test.cpp. The file would still be compressed & decompressed correctly. This has been fixed in the repo.

Note this issue did not impact the test mode (the default) when the same file was specified.
