Title: Fixed arithmetic operations and added tests for them

Arithmetic operations used to pass the "Bits" value to the constructor of the newly constructed ByteSize instance instead of "Bytes" resulting in wrong calculations. Operations now pass the right value to the constructor.

Added some simple test cases to ensure arithmetic functions now work as expected.
