bytesutil

Utilities for reducing memory allocations in Go w/ 100% unit test coverage.

• Zero-allocation conversion between string and byte slice.
• Zero-allocation signed/unsigned variable integer encoding/decoding.
• Zero-allocation signed/unsigned 64-bit/32-bit/16-bit integer encoding/decoding.
• Extend slice to a sufficient length.
