zipada 60.0.0 (#1294)

New feature: added compression for the BZip2 format for .bz2 and .zip files or streams.

Note that Zip-Ada now tops (or rather, bottoms ;-) in terms of compressed size) 7-Zip for both Calgary (*) and Canterbury benchmarks, for the .zip format and even the .7z format.

+
+Zip-Ada is a free, open-source programming library for dealing with the Zip compressed archive file format.
+The full sources of Zip-Ada are in Ada, compilable on every compiler and for every system (*).
+
+Key features of Zip-Ada:
+
+* Files and streams supported, for archives and entries, for compression and decompression
+* Task safe
+* Endian-neutral
+* Standalone
+* Zip methods supported for compression: Reduce, Shrink, Deflate, BZip2, LZMA.
+* Zip methods supported for decompression: the above methods, plus: Implode, Deflate64
+* Library is in pure Ada 2012 (nothing compiler/system specific), can be used in projects in Ada 2012 and later versions of the language
+* Unconditionally portable (*)
+* Tests and demos included
+
+The library includes LZMA & BZip2 independant compressor & decompressor pairs
+(can be used outside of the Zip archive context).
+

+
+(*) within limits of compiler's provided integer types and target architecture capacity.
