Tests: Add fuzz_decode_alone OSS-Fuzz target This fuzz target that handles LZMA alone decoding. A new fuzz dictionary .dict was also created with common LZMA header values to help speed up the discovery of valid headers.

Tests: Minor cleanups to OSS-Fuzz files. Most of these fixes are small typos and tweaks. A few were caused by bad advice from me. Here is the summary of what is changed: - Author line edits - Small comment changes/additions - Using the return value in the error messages in the fuzz targets' coder initialization code - Removed fuzz_encode_stream.options. This set a max length, which may prevent some worthwhile code paths from being properly exercised. - Removed the max_len option from fuzz_decode_stream.options for the same reason as fuzz_encode_stream. The alone decoder fuzz target still has this restriction. - Altered the dictionary contents for fuzz_lzma.dict. Instead of keeping the properties static and varying the dictionary size, the properties are varied and the dictionary size is kept small. The dictionary size doesn't have much impact on the code paths but the properties do. Closes: https://github.com/tukaani-project/xz/pull/73
