d2bist

CLI utility to handle data as binary strings

The need behind it is to have a quick way to visualize programs as binary string while playing around with AIT

• Convert data to a binary string of 0 and 1
• Statistical analysis of 0 and 1 distributions
  • Number of bit string of variable length (0, 00, 000, 0000, 1, 11, 111, 1111 and so on)
• Visualize binary string as image
• Support online compression and decompression

Examples
