This PR introduces the PythonParser class, which utilizes the web-tree-sitter library to analyze Python code. The main features added in this PR include:

Initialization of Tree-Sitter Parser:

The PythonParser class initializes a web-tree-sitter parser for Python using the tree-sitter-python grammar.
It loads the WebAssembly module (tree-sitter-python.wasm) to set up the parsing environment.

Finding Enclosing Context:

The findEnclosingContext method identifies the largest enclosing function or class definition given a range of lines.
This method provides context information about the type (function, async function, or class), name, and location of the enclosing code block.
Syntax Validation:

The dryRun method performs a syntax check on the provided Python code.
It parses the code to identify any syntax errors and returns whether the code is valid or not.
