Function bytesLenUnsafe

bytesLenUnsafe(hex: `0x${string}`): number
Fast byte length for Hex strings.

This function efficiently calculates the byte length of Hex values:
- Skips isHex validation (caller must ensure input is valid Hex)
- Handles odd-digit hex by rounding up, matching bytesFrom's padding behavior.
Parameters
- hex: `0x${string}`
  A valid Hex string (with "0x" prefix).
Returns number
Byte length of the hex string.
Example
```
bytesLenUnsafe("0x48656c6c6f") // 5
bytesLenUnsafe("0x123") // 2 (odd digits round up via padding)
```
