Utility functions to initialize parameters and state variables from a file.

[edwardalee]

This PR adds utility functions to initialize parameters and state variables from a file.
The file can be a CSV file (or use any other single-character delimiter) and the program can choose a row from the file to initialize any number of parameters and/or state variables of the same type from the specified row.
The types supported are double, int, and string.

Pull request overview

This PR introduces a small C utility for initializing Lingua Franca C-target parameters/state variables from a delimited text file (e.g., CSV) by reading a selected row and parsing values into provided double* outputs.

Changes:

• Added lf_initialize_double() API and implementation to read/parse a delimited row into variadic double* outputs.
• Added a CMake include snippet to compile the new utility source into the main target.
• Fixed documentation examples in deque headers/source to include the missing comma in target C { ... } examples.
