Rearrange the CV draft extension's values enum

[robbert-vdh]

Super minor nitpick, but if this design ends up being used, then I'd propose the generic CLAP_CV_VALUE to be the first value in the list. Otherwise if you end up adding more useful standardized CV types in the future, it would end up somewhere in the middle of the list.

clap/include/clap/ext/draft/cv.h

Lines 17 to 22 in 75dabe9

	enum {
	// TODO: standardize values?
	CLAP_CV_GATE = 0,
	CLAP_CV_PITCH = 1,
	CLAP_CV_VALUE = 2,
	};

Good catch.
And VALUE is a good default after memset(0).
