Optimized invalid curve generation, added optional args to gen_t

- Optimized invalid curve generation
   - Invalid curve generation for secp256r1 now takes around 90minutes
     instead of 5hours as before
- Optimized prime point generation(if only some small prime order
   points are needed -> points_primet)
- Added a_once and b_once that prompt for parameter input and then set
   the input parameter repeatedly
- Added optional args to gen_t functions
- Integer input now ignores whitespace and doesnt errorneously prompt
   stdout when reading from file
- Specified C standard(C11) + feature macros in code.
