Class: HmacSigner

The real TuyaSigner: sign = HMAC-SHA256(K, preimage) as lowercase hex.

Uses TUYA_SIGN_K by default — no configuration required. The env var TUYA_SIGN_KEY overrides the built-in key (for custom builds); an explicit constructor argument takes precedence over both. Verified: reproduces the captured smartlife.p.time.get sign 97a78b35…a7f8c84.
