refactor(capi): redesign the C API using callbacks (#198)

Instead of allocating a `YRX_PATTERNS` structure with patterns and matches, the API offers functions that allow iterating over the patterns using callback functions. With this design the allocation of memory is not necessary. The implementation is also split into more files for making the code easier to maintain.
