Function parseString

parseString(
    qasm: string,
    version?: number | OpenQASMVersion,
    verbose?: boolean,
    stringify?: boolean,
): any
Parses OpenQASM code from a string and returns the abstract syntax tree.

This is the primary entry point for parsing OpenQASM code. It handles both OpenQASM 2.0 and 3.0 syntax, automatically selecting the appropriate lexer and parser based on the version parameter.
Parameters
- qasm: string
  The OpenQASM code string to parse
- Optionalversion: number | OpenQASMVersion
  The OpenQASM version to use (defaults to 3.0)
- Optionalverbose: boolean
  Whether to include class names in the output (defaults to false)
- Optionalstringify: boolean
  Whether to return stringified JSON (defaults to false)
Returns any
The corresponding AST as an array of nodes, or stringified JSON if stringify is true
Example: Basic OpenQASM 3.0 parsing
```
import { parseString } from 'qasm-ts';

const qasmCode = `
OPENQASM 3.0;
include "stdgates.inc";
qubit[2] q;
h q[0];
cx q[0], q[1];
`;

const ast = parseString(qasmCode);
console.log(ast);
```
Example: OpenQASM 2.0 parsing
```
const qasm2Code = `
OPENQASM 2.0;
include "qelib1.inc";
qreg q[2];
creg c[2];
h q[0];
cx q[0],q[1];
measure q -> c;
`;

const ast = parseString(qasm2Code, 2);
```
Example: Verbose output with class names
```
const ast = parseString(qasmCode, 3, true);
// Output will include __className__ properties for each node
```
