Implement v2.0 API for easier CBOR encoding/decoding. See issue #117 for summary. Replaced EncOptions.TimeRFC3339 bool with TimeMode values: * TimeUnix // secs, converted to smallest CBOR integer that fits * TimeUnixMicro // μs, CBOR float with subsecs in fractional part * TimeUnixDynamic // secs or μs, either int or float depending on empty subsecs * TimeRFC3339 // secs, string * TimeRFC3339Nano // ns, string with trailing zeros removed Decode CBOR time NaN and Infinity values to Go's "zero time" value. This is how CBOR Null values are decoded to time.Time. Removed deprecated options (Canonical & CTAP2Canoical) in EncOptions. Removed Valid() function. Improved performance and memory alloc by * using pointer receivers for types implementing sort.Interface and others. * storing pointer in sync.Pool. * storing pointer as map value in sync.Map. Used roughly 20 linters and resolved many reported issues. Switched to GitHub Actions for CI to lint, test, and check code coverage. Extensive improvements to README.md. Thanks @x448 for API design ideas, travis & github ci configs, filing issues, and improving README.md. Closes: #107 Closes: #119 Closes: #120 Closes: #123 Closes: #124 Closes: #127
