/**
 * Converts arbitrary values into integers using extended conversion rules:
 * - Strings are converted to floats, then to integers
 * - DateTime: total number of milliseconds since unix epoсh
 * - Boolean: 1 for true and 0 for false
 *
 * ### Example ###
 *
 *     let value1 = IntegerConverter.toNullableInteger("ABC"); // Result: null
 *     let value2 = IntegerConverter.toNullableInteger("123.456"); // Result: 123
 *     let value3 = IntegerConverter.toNullableInteger(true); // Result: 1
 *     let value4 = IntegerConverter.toNullableInteger(new Date()); // Result: current milliseconds
