Convert a byte array to a String with a hexidecimal format.
The String may be converted back to a byte array using fromHexString.
For each byte (b) two characaters are generated, the first character
represents the high nibble (4 bits) in hexidecimal (b & 0xf0), the second character
represents the low nibble (b & 0x0f).
The byte at data[offset] is represented by the first two characters in the returned String.
