Added tons of opcode documentation, changed license to ISC and a lot of file refactoring.

+* @file value.h
+ * @brief Defines the Value type and associated functions for the Fun VM.
+ *
+ * This file defines the `Value` type, which represents all possible data types
+ * in the Fun language, including integers, strings, functions, arrays, maps, and nil.
+ * It also provides utility functions for creating, copying, and freeing `Value` objects.
+ *
+ * Key Types:
+ * - `ValueType`: Enumeration of supported value types (e.g., `VAL_INT`, `VAL_STRING`).
+ * - `Value`: Union type that can hold any Fun value.
+ *
+ * Functions:
+ * - `make_int`, `make_string`, `make_function`, `make_nil`: Constructors for `Value`.
+ * - `array_length`, `array_get_copy`, `array_set`: Array manipulation functions.
+ * - `make_map_empty`, `map_set`, `map_get_copy`: Map manipulation functions.
+ * - `copy_value`, `deep_copy_value`, `free_value`: Functions for copying and freeing values.
+ *
+ * Example:
+ * ```c
+ * Value num = make_int(42);
+ * Value str = make_string("Hello, Fun!");
+ * ```
