v1.0.0

• Reworded documentation where it improved clarity.
• Completely removed dynamic memory allocation, except where requested by the user (i.e. in hdrbg_init).
  • This required creating upto 93-element arrays on the stack and a 65536-element global static array, which any modern system should be able to handle easily.
  • In line with the same, checks for failure to allocate memory were removed.
• Updated function signatures in headers to match the way the definitions are written.
• Python module docstring placed in a variable.
• Code readability improvements.
