Remove #[inline(always)] from CompressorOxide::default() (#125)

With #[inline(always)] the body of default() will be inlined into
external crates but the body will still contain calls to the
LZOxide::new(), ParamsOxide::new(DEFAULT_FLAGS), Box::default() and
DictOxide::new(DEFAULT_FLAGS). This ends up causing a copy of the large
LZOxide to end up on the stack when used with Box::default as seen in:
rust-lang/rust#101814
