Dynamic QR Code Generator with Optimal Sizing

Build a QR code generation utility that automatically handles variable-length input data by selecting the optimal QR code size.

Requirements

Your system should generate QR codes that automatically adjust their size based on the amount of data being encoded. The system must efficiently handle both short and long data inputs without requiring manual version selection.

Core Functionality

Implement a function that:

• Accepts text data of any length as input
• Generates a QR code image that is automatically sized to fit the data
• Saves the generated QR code to a specified output file path
• Uses medium error correction level for reliability

Size Optimization

The system must:

• Automatically determine the minimum QR code version needed for the input data
• Handle data ranging from short URLs (10-20 characters) to longer text (200+ characters)
• Start the version search from version 1 to ensure the smallest possible code

Test Cases

• Given the text "https://example.com", the function generates a valid QR code image saved to the specified path @test
• Given a 250-character text string, the function generates a valid QR code image without raising errors @test
• The generated QR code file exists and is a valid image file @test
