Function convertGroupedSmmParametersToTransmitData

Converts a grouped map of SMM parameters/values into a flat array suitable for transmission.

During transmission, the Safety-Limited Speed (SLS) groups must be transposed. That is, instead of sending the values grouped by SLS1, SLS2, SLS3, and SLS4 in order, the values are interleaved such that:

Input:

• SLS1: [a1, a2, a3, ...]
• SLS2: [b1, b2, b3, ...]
• SLS3: [c1, c2, c3, ...]
• SLS4: [d1, d2, d3, ...]

Output:

• [a1, b1, c1, d1, a2, b2, c2, d2, a3, b3, c3, d3, ...]

This function:

• Accepts an object mapping group names to arrays of parameters/values (e.g., "Safety functions (SOS)", "SLS1", etc.).
• Locates the starting index of the SLS groups by finding the first key that includes "SLS".
• Extracts and transposes the four SLS groups into n arrays of 4 elements each.
• Inserts the transposed data in place of the original SLS groups.
• Preserves the order of all other groups before and after the SLS block.
• Returns the entire structure as a flattened one-dimensional array.

Returns

A flat array of all parameter values, reordered for transmission.
