Heavily optimize memory allocations Uses a memory pool for parser struct and format []byte Uses a new go 1.20 feature to avoid allocations for []byte to string conversions in allowable cases. go 1.20 also fixes a go bug for parsing fractional sec after a comma, so we can eliminate a workaround. The remaining allocations are mostly unavoidable (e.g., time.Parse constructing a FixedZone location or part to strings.ToLower). Results show an 89% reduction in allocated bytes for the big benchmark cases, and for some formats an allocation can be avoided entirely. There is also a resulting 26% speedup in ns/op.
