vgminfo v1.1: Improved chip detection using hybrid approach

- Fixed missing chip detection (e.g., SN76489 in SHIRAKAW.VGM)
- Fixed false positive detection (e.g., AY-3-8910 in files without it)
- Implemented hybrid detection strategy:
  * Check VGM header clock values (offsets 0x0C, 0x2C, 0x30, 0x74) to
    determine which chip types are present
  * Scan VGM command stream (up to 255 commands) to detect multiple
    instances of same chip type (e.g., '2xSN76489')
- Added VGM version check: only read AY-3-8910 clock for VGM v1.51+
  to avoid false positives from invalid data in earlier versions
- Updated documentation with new detection approach and examples

Add VGMINFO.COM utility for CP/M

This utility scans .VGM files in the current directory and displays which sound chips they use. Useful for determining VGM compatibility with RomWBW's VGM player.

Features:
- Scans all .VGM files in current directory
- Detects SN76489, YM2612, YM2151, and AY-3-8910 chips
- Displays results in a formatted table
- Supports dual-chip configurations

Could you please integrate this into the RomWBW build process alongside the existing VGM player utilities?
