The current min/max/def constructor is insufficient,\nas .values() is empty, so the values cannot be easily iterated over, and\ncreating a Span of booleans does not work for the values constructor.\n\nAdd new constructors to ControlInfo that takes a set of booleans (if\nboth booleans are valid values) plus a default, and another that takes\nonly one boolean (if only one boolean is a valid value).\n\nUpdate the ControlInfo test accordingly.\n\nSigned-off-by: Paul Elder <paul.elder@ideasonboard.com>\n\n---\nChanges in v5:\n- break away the single-value one to a different constructor\n\nChanges in v2:\n- use set instead of span of bools\n- add assertion to make sure that the default is a valid value\n- update the test\n---\n include/libcamera/controls.h   |  3 +++\n src/libcamera/controls.cpp     | 29 +++++++++++++++++++++++++++++\n test/controls/control_info.cpp | 33 +++++++++++++++++++++++++++++++++\n 3 files changed, 65 insertions(+)",
