Extension method

ToByteString- Converts byte to byte[] considering the byte as a BigInteger (0x00 at the end).
- Converts sbyte to byte[].
- Converts string to byte[]. Examples: "hello" -> [0x68656c6c6f]; "" -> []; "Neo" -> [0x4e656f]
- Converts byte[] to string. Examples: [0x68656c6c6f] -> "hello"; [] -> ""; [0x4e656f] -> "Neo"
WithinReturns true if a <= x && x < b. Examples: x=5 a=5 b=15 is true; x=15 a=5 b=15 is false
ConcatConcatenates two byte arrays
RangeCopies the subarray, starting from the specified position and having the specified length
TakeReturns a specified number of contiguous elements from the start of a sequence
LastReturns a specified number of contiguous elements from the last of a sequence
