Create Agilent/Rigol pattern waveform parser

feat(patterns): add Agilent/Rigol wavebin waveform parser

Adds a new Pattern Language script to parse .bin waveform files exported from Agilent, Keysight, and Rigol oscilloscopes.

Features:

• Supports File Header versions 1, 3, and 10.
• Parses nested Waveform and Data headers.
• Automatically handles variable-length data buffers (float32 and u8).
• Includes auto-load pragmas for magic bytes 'AG' and 'RG'.
• Organizes sample data into inspectable arrays in the Pattern Data view.

Based on https://github.com/sam210723/wavebin/

Thanks a lot! Could you also upload a test file under tests/patterns/test_data/wavebin.hexpat.bin and add your pattern to the table in the readme?

Also fyi, the magic byte detection using [ 41 47, 52 47 ] doesn't work like that. You can however add two #pragma magic statements, one for each of the two sequences you want to match for
