Pull Request Overview

This PR adds functionality to send synthesizer patches via MIDI Control Change (CC) messages. The feature enables users to apply a patch file (.prm) to a synthesizer by converting patch parameters to appropriate CC messages and sending them through MIDI.

• Added a new CLI command send-patch to apply patch files to the synth through MIDI
• Implemented CC message generation logic in the JU06AState class
• Added parameter scaling logic to handle different value ranges between patch files and CC messages

The division by 2 for double attributes lacks explanation. Consider adding a comment explaining why these values need to be halved for CC transmission.

Suggested change

	if patch_attribute in DOUBLE_ATTRIBUTES:
	if patch_attribute in DOUBLE_ATTRIBUTES:
	# Double attributes have a range of 0..255 at the synth level, but MIDI CC messages only support 0..127.
	# Therefore, we divide by 2 to fit the value into the MIDI CC range for transmission.
