⬆️ Bump Go 1.19 + Echo v4.9 + set `GOAMD64=v3`

[0uep]

• Bump Echo from v4.1.17 to v4.9.0.
• Bump Go from 1.15 to 1.19: Each Go version improves the performance, between Go-1.15 and Go-1.19 I expect some little gains.
• Set GOAMD64=v3 to enable the following instructions set: CMPXCHG16B, LAHF, SAHF, POPCNT, SSE3, SSE4.1, SSE4.2, SSSE3, AVX, AVX2, BMI1, BMI2, F16C, FMA, LZCNT, MOVBE, OSXSAVE. The default value is GOAMD64=v1. See https://github.com/golang/go/wiki/MinimumRequirements#amd64
