Add support for writing struct arrays to excel table

[d9c4]

PR Details

Adds support for exporting slices of tagged structs to Excel in a tabular format.

Description

Add support to quickly write a slice of structs on an Excel table. The feature uses generics and tags.
Fields are read via struct tags and written as column headers. Supports basic types and nested types.

Related Issue

Motivation and Context

This feature was added to simplify the process of exporting data to Excel. Previously, generating a table required manual formatting for each dataset. Now, struct tags and generics can be used to define headers and structure, reducing repetitive code and improving maintainability.

How Has This Been Tested

Unit tests were added in this commit for the added features.

Usage example

Code usage

	Column2 string `column:"B" columnHeader:"Column 2"`
}
var testStructs = []testStruct{
	{Column1: "1", Column2: "2"},
	{Column1: "3", Column2: "4"},
}
WriteStructsIntoFile(f, testStructs, &ModelTableOptions{HasHeader: true})

Column 1	Column 2
1	2
3	4

Thanks for your pull request. I recommend user to using SetSheetRow function instead of this. Users can easily make this wrapper and even create their own complex nested structure. I didn't suggest introducing this feature to make the library core and easy.
