Mutation Based Fuzzer

jpg2bmp is a program which converts images files from '.jpg' format to '.bmp' format. This target program consists of 8 hidden bugs which is to be found out using mutation based fuzzing.
mutate.py is a mutation based fuzzer which takes a valid input (eg: cross.jpg) for the target program 'jpg2bmp', mutates the input in different ways, and tests the mutated input by feeding it to the target program to find out the hidden bugs.
To run the program simply run

$ python mutate.py

All of the test files which trigger a bug are archived in the 'archive' directory at the end of the program.
mutate.py also produces a report 'report.json' at the end of the program which can be found inside the 'archive' directory at the end of the program. It gives a count for each of the following
```
 "num_of_test_files": 
 "num_of_bugs_trigerred": 
 "bug1_count": 
 "bug2_count":
 "bug3_count":
 "bug4_count":
 "bug5_count": 
 "bug6_count":
 "bug7_count": 
 "bug8_count": 
```
