Fix bulk import

[dave-mills]

This PR fixes a bug with the project/initiative importer, and improves the import to bring in continents, regions and countries.

DONE:

• turned the import template into a dynamic export, to account for future updates to dropdown lists like initiative categories and geographic reach.
• added initiative categories and locations to the import. These are handled by comparing name strings.

PR Summary

• Introduction of various new files for data exports The PR includes the addition of new files namely CountriesExportSheet.php, GeographicReachesExportSheet.php, InitiativeCategoryExportSheet.php, InitiativeImportTemplateExportSheet.php, and YesNoExportSheet.php. They serve different purposes such as generating collections of countries, geographic reaches and yes/no values, and managing export data for initiative categories and import templates. Each file contains methods defining how the data is prepared and organized for the sheet exports.

• Update on 'ImportOperation.php' and 'ProjectCrudController.php' files for improved data import The ImportOperation.php file was tweaked to generate import templates using the new InitiativeImportTemplateExportWorkbook class. In the ProjectCrudController.php file, properties were adjusted to use this new class for generating templates and setting template file names.

• Enhancements on 'ProjectImport.php' and 'ProjectWorkbookImport.php' The PR has tailored the ProjectImport.php file to implement the OnEachRow interface and included logic for handling location-related data (continents, regions, countries) for initiatives. The ProjectWorkbookImport.php file was also adjusted to specifically use the new 'initiatives' name for importing projects.

• 'composer.json' adjustments Certain packages were updated and moved around in the composer.json file - maatwebsite/excel package was updated, barryvdh/laravel-ide-helper package was shifted from 'require-dev' section to 'require' section, and a new package spatie/laravel-ray was added to 'require-dev' section.

Overall, these changes are aimed at improving the data export capabilities and streamline the import process.
