lib/{decimal,encoding}: optimize float64<->decimal conversion for arrays with zeros or ones
...
Time series with only zeros or ones frequently occur in monitoring, so it is worth optimizing their handling.

lib/encoding/zstd: disable CRC checks in pure Go build
...
This should give slightly better compression and decompressions performance.
Additionally this shaves off 4 bytes per each compressed block.

lib/encoding: improve gauge series detection
...
- Series with negative values are always gauges
- Counters may only have increasing values with possible counter resets
This should improve compression ratio for gauge series which
were previously mistakenly detected as counters.
