/**
 * Converts a given number with an arbitrary sign bit position
 * into an ordinary (signed) JavaScript integer.
 * For example, if `highBit` is 6 and `bitsStores` = 5,
 * the number is stored like `0bxSNNNNxx`, where `S` is the sign bit
 * and `x` is the unused bits, which will be ignored.
 * @param input A number using 2's complement
 * @param bitsStored DICOM "Bits Stored" value,
 * which describes how many bits are used to represent a number,
 * counting from `highBit` (between 2 to `highBit` + 1).
 * @param highBit DICOM "High Bit" value,
 * which is the position of the sign bit (between 0 and 31)
