The Color algorithm was tweaked to:
a) not produce incorrect values if the user happens to input a hue outside the [0, 180) range, and
b) more accurately convert the hue remainder from range 0-30 to 0-255. The current conversion vastly overshoots the multiplier (converts 0-30 to 0-270) and relies on clamping the value when constructing the Color object to produce a slightly incorrect result.
Comparison operators which compared against every class member variable
now use C++20's default comparison operators.
Also remove operator!= that in C++20 is now auto-generated from operator==.
This makes code easier to read and more consistent between C++ and Java.
Also update clang-format settings to always add a line break (even if no braces are used).
Both floating point and 8-bit integer classes are included, as well as a wide selection of color constants.
