Subject: [PATCH 10/11] fix: complete VSRI implementation and improve code
 quality

VSRI Fixes:
- Fix float division bugs in get_sample() and fits_segment()
- Improve error handling in load() - replace unwraps with proper error propagation
- Document MAX_INDEX_SAMPLES as configurable
- Fix doc test imports and empty line after doc comment

Code Quality Improvements:
- Replace BinConfig struct with bincode_config() function
- Remove unused POLYNOMIAL_COMPRESSOR_ID and IDW_COMPRESSOR_ID constants
- Remove unused vsri import from main.rs
- Fix clippy warnings (needless borrows, into_iter on ref)

All tests passing (85 tests total)
Clippy clean with -D warnings

Subject: [PATCH 11/11] fix: address PR review - complete VSRI
 serialization/deserialization

Fixes identified in PR #150 review:

1. **VSRI Frame Tagging**: CompressorFrame::compress_vsri now correctly
   sets self.compressor = Compressor::VSRI so VSRI data is properly
   tagged in serialized files

2. **VSRI Decompression**:
   - Added CompressorFrame::decompress_vsri() method
   - Added CompressedStream::decompress_vsri() method
   - Added CompressorFrame::is_vsri() helper method
   - VSRI files can now be round-tripped successfully

3. **CLI Safety**: Removed VSRI from CompressorType enum to prevent
   users from selecting --compressor=vsri which would cause panic
   - VSRI is for internal timestamp compression only
   - Not applicable to f64 data compression

4. **Better Error Handling**: Changed Compressor::decompress VSRI case
   from panic to log warning and return empty vec, allowing graceful
   handling if VSRI frame is accidentally processed as f64

Testing:
- Added test_vsri_roundtrip test to verify complete cycle
- All 86 tests passing
- Clippy clean with -D warnings
