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,decimal}: add benchmarks for blocks containing zeros or ones
...
Time series with such values are quite common in monitoring space,
so it would be great to have benchmarks for them.

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.
