-// Notes for version 1.1:
-/*  1. Tiny data compression integrates several compression modes: fixed
-    bit, text mode, single value, string mode, and 7-bit encoding and
-    decoding. td64 returns the number of compressed bytes or 0 if
-    compression failed or a negative value if an error occurred. Values
-    are returned only if compression succeeds. Decoding of the td64 values
-    requires the caller to supply the number of original bytes.
