deps: bump lzma-rust2 from 0.18.1 to 0.20.0

[dependabot]

Bumps lzma-rust2 from 0.18.1 to 0.20.0.

Changelog

Sourced from lzma-rust2's changelog.

0.20.0 - 2026-08-23

Added

• Add new_mem_limit() to Lzma2Stream and XzStream.
• Add set_filters() to Lzma2Stream and LzmaStream, so both can decode through a BCJ or delta pre-filter. At most one filter is supported.
• Add filter::StreamFilter, which decodes a slice in place through a single BCJ or delta filter.

Changed

• Decode LZMA2 chunks as they arrive instead of buffering each one, so Lzma2Stream and XzStream produce output sooner and use less memory.
• A truncated stream now comes back as UnexpectedEof from the sans-I/O decoders instead of InvalidData.
• FilterConfig and FilterType no longer need the xz feature.

Fixed

• Lzma2Stream and XzStream now fail every later process() call once one has returned an error, like LzmaStream already did.

0.19.0 - 2026-08-16

• Add sans-I/O decoders for LZMA1 and LZIP. Thanks @​Black-Frost (#109)
