Mary feat: add LZMA1 streaming decoder 2mo ago

commons-compress

feat: add LZMA1 streaming decoder ports the range decoder, LZ window, and the LZMA arithmetic model from hasenbanck/lzma-rust2 (itself a port of tukaani's xz-for-java). the state machine, literal coder, match-len coder, and rep-len coder all match the reference; only the streaming wrapper diverges to fit the StreamReader-shaped byte source the rest of this library already uses. the range decoder buffers its input internally and throws RangeUnderflow when the caller hasn't fed enough bytes. the public decodeLzmaStream async generator catches that signal, refills from the source, and resumes — the LZMA state is rolled back to the start of the in-flight decode step before the underflow. tested against three .lzma fixtures generated with /usr/bin/lzma: small lipsum, 285 KB of repeated lorem, and 11 KB of English prose. all roundtrip to byte-identical plaintext.
