stdlib: std::compression::zip and std::compression::deflate (#2930)

* stdlib: implement `std::compression::zip` and `std::compression::deflate`

- C3 implementation of DEFLATE (RFC 1951) and ZIP archive handling.
- Support for reading and writing archives using STORE and DEFLATE
methods.
- Decompression supports both fixed and dynamic Huffman blocks.
- Compression using greedy LZ77 matching.
- Zero dependencies on libc.
- Stream-based entry reading and writing.
- Full unit test coverage.

NOTE: This is an initial implementation. Future improvements could be:

- Optimization of the LZ77 matching (lazy matching).
- Support for dynamic Huffman blocks in compression.
- ZIP64 support for large files/archives.
- Support for encryption and additional compression methods.

* optimizations+refactoring

deflate:
- replace linear search with hash-based match finding.
- implement support for dynamic Huffman blocks using the Package-Merge
algorithm.
- add streaming decompression.
- add buffered StreamBitReader.

zip:
- add ZIP64 support.
- add CP437 and UTF-8 filename encoding detection.
- add DOS date/time conversion and timestamp preservation.
- add ZipEntryReader for streaming entry reads.
- implement ZipArchive.extract and ZipArchive.recover helpers.

other:
- Add `set_modified_time` to std::io;
- Add benchmarks and a few more unit tests.

* zip: add archive comment support

add tests

* forgot to rename the benchmark :(

* detect utf8 names on weird zips

fix method not passed to open_writer

* another edge case where directory doesn't end with /

* testing utilities

- detect encrypted zip
- `ZipArchive.open_writer` default to DEFLATE

* fix zip64 creation, add tests

* fix ZIP header endianness for big-endian compatibility

Update ZipLFH, ZipCDH, ZipEOCD, Zip64EOCD, and Zip64Locator structs to
use little-endian bitstruct types from std::core::bitorder

* fix ZipEntryReader position tracking and seek logic ZIP_METHOD_STORE

added a test to track this

* add package-merge algorithm attribution

Thanks @konimarti

* standalone deflate_benchmark.c3 against `miniz`

* fix integer overflows, leaks and improve safety

* a few safety for 32-bit systems and tests

* deflate compress optimization

* improve match finding, hash updates, and buffer usage

* use ulong for zip offsets

* style changes (#18)

* style changes

* update tests

* style changes in `deflate.c3`

* fix typo

* Allocator first. Some changes to deflate to use `copy_to`

* Fix missing conversion on 32 bits.

* Fix deflate stream. Formatting. Prefer switch over if-elseif

* - Stream functions now use long/ulong rather than isz/usz for seek/available.
- `instream.seek` is replaced by `set_cursor` and `cursor`.
- `instream.available`, `cursor` etc are long/ulong rather than isz/usz to be correct on 32-bit.

* Update to constdef

* Fix test
