Function render_edifact 

pub fn render_edifact(
    segments: &[DisassembledSegment],
    delimiters: &EdifactDelimiters,
) -> String

Render a list of disassembled segments into an EDIFACT string.

Follows the same rendering rules as RawSegment::to_raw_string:

• Elements separated by element separator (+)
• Components separated by component separator (:)
• Trailing empty elements are trimmed
• Each segment terminated by segment terminator (')
