fix: add 'core' export and mapping for single files

[jboix]

Description

Introduces a new export under the core mapping to facilitate the use of the core functionalities of the pillarbox library. Integrators can now easily access the core bundle by importing it directly in their projects as shown below:

// Using ES6 import syntax
import pillarbox from '@srgssr/pillarbox-web/core';

// Using CommonJS syntax
const pillarbox = require('@srgssr/pillarbox-web/core');

This update also includes an export to allow for straightforward mapping of all files included in the final bundle.

Changes made

• Additional mappings in the export option of the package.json.
