Library for streamlined file management and advanced data caching, featuring intelligent file searching, dynamic cache control, and flexible file operations

### File Class Constructor

#### Overview:
The `File` class constructor creates an instance of `File`, designed to manage a file within a specified directory. It supports validation, caching, and data management of the file.

#### Constructor Parameters:

1. **`path` (String, required)**: The path to the directory where the file is located. This parameter specifies the file's location in the file system but does not include the file name itself.

2. **`name` (String, required)**: The name of the file. It is used for identifying and managing the file within its directory.

3. **`schema` (Schema, optional)**: An instance of the `Schema` class used for generating file parameters from its name and vice versa. The schema allows for the transformation of the file name into a structured set of data (e.g., `{name: 'Alex Smith', age: 25}` from the file name `Alex Smith.25`) and ensures data validation.

#### Functionality Description:

- When creating a `File` instance, the constructor initializes key properties of the file, such as path, name, and size.
- If a schema is provided for the file, it is used to generate parameters from the file name and to convert parameters back into a name.
- The constructor also manages the addition of the file to the cache, updating the size of cached data and ensuring efficient memory usage.

#### Usage Example:

```js
const file = new File('/path/to/directory', 'example.txt', userSchema);
```
