Contributor guide

Research direction
Check if easyexcel's CellStyle supports custom colors via XSSFColor or HSSFColor. If not, implement a method to set fill foreground color using custom RGB values. Review the existing ColorIndex enum for reference and propose a new API such as setFillForegroundColor(Color customColor).
