feat(devins-language): add method to create DevInFile #101

Add a new method `fromString` to create a `DevInFile` from a given text in DevIn language. This method creates a new file with a unique filename using UUID, and then returns the created `DevInFile`. This method improves the flexibility and reusability of creating `DevInFile` instances.
