Maximum 'switch' branches

Reports switch statements or expressions with too many case labels.

Such a long switch statement may be confusing and should probably be refactored. Sometimes, it is not a problem (for example, a domain is very complicated and has enums with a lot of constants).

Example:

switch (x) {
    case 1 -> {}
    case 2 -> {}
    case 3 -> {}
    case 4 -> {}
    case 5 -> {}
    case 6 -> {}
    case 7 -> {}
    case 8 -> {}
    case 9 -> {}
    case 10 -> {}
    case 11,12,13 -> {}
    default -> {}
}

Use the Maximum number of branches field to specify the maximum number of case labels expected.
