New Proposal: Map Data Type

[rouzbehsbz]

This pull request introduces a new Map data type to the Chap language.
The syntax follows a hash-table–like structure, for example:

{"alpha":1 "bravo":"string" "charlie":true}

• Added a new Map data type to the language core.
• Implemented parsing and runtime support for map literals.
• Introduced a new shared module for common collection operations.
• Refactored list and map to use this shared functionality.

Moved and rewrote the following operations so they are now shared across both data types:

• get
• has
• insert
• remove

There is a known issue with parsing nested objects and arrays due to the current parsing approach

Motivation

Add more useless features to the language, following Chap’s ideology
