Fix documentation issues and update dependencies

- Added missing @description in update.state.LPJGUESS.R to fix roxygen2 errors.
- Included @name and @title for split_inputs.LPJGUESS.R to generate .Rd files correctly.
- Updated NAMESPACE to include proper imports for missing dependencies (PEcAn.utils, etc.).
- Resolved missing dependencies in DESCRIPTION (stringr).
