Represent serial numbers using SerialNumber struct
In a previous commit, we changed the serial number representation from a string to an integer. This made it easier to compare serial numbers, but also introduced new problems: - Serial numbers should be formatted consistently, for example as "{:#010x}". It is hard to ensure this for an integer value. - The format of the serial number may be subject to change. Users should not rely too much on the u32 representation. Therefore we introduce a new SerialNumber struct that represents a serial number. Currently it only stores a u32 value. The following traits and functions can be used to access its value: - FromStr for string parsing - ToString/Display for string formatting - as_u32 to access the underlying integer value
